The first iteration always do `m[0], m[0] = m[0], m[0]`, because
`rand.Intn(1)` is 0.
fun note: IIRC in TAOCP version of this algorithm, `i` goes
backward (n-1->1), meaning that the "already" shuffled part of the
array is never altered betweens iterations, while in the current
implementation the "not-yet" shuffled part of the array is
conserved between iterations.

64bit atomics are broken on 32bit systems. This is issue 599.
linux/arm builders all broke with this change, I am concerned that the other 32bit builders are silently impacted.

When a race happens inside of runtime (chan, slice, etc),
currently reports contain only user file:line.
If the line contains a complex expression,
it's difficult to figure out where the race exactly.
This change adds one more top frame with exact
runtime function (e.g. runtime.chansend, runtime.mapaccess).

RFC 2616: "The 204 response MUST NOT include a message-body,
and thus is always terminated by the first empty line after
the header fields."
Previously we'd trigger chunked encoding by default on
responses, and then when finishing the request we'd write the
chunk trailers, which counted as a message-body.

1) Built-ins are restricted like for expression statements.
This documents the status quo.
2) Calls cannot be parenthesized. The spec is not clear. gccgo
permits it already, gc doesn't. Be explicit in the spec.

Update #4434.
The proposal attempts to reduce the number of places where fd,{r,w}deadline is checked and updated in preparation for issue 4434. In doing so the deadline logic is simplified by letting the pollster return errTimeout from netFD.Wait{Read,Write} as part of the wakeup logic.
The behaviour of setting n = 0 has been restored to match rev 2a55e349097f, which was the previous change to fd_unix.go before CL 6851096.

Garbage collection code (to be merged later) is calling functions
which have many local variables. This increases the probability that
the stack capacity won't be big enough to hold the local variables.
So, start gc() on a bigger stack to eliminate a potentially large number
of calls to runtime·morestack().

The syslog implementation was not correctly implementing the
traditional syslog format because it had a confused notion of
'priority'. syslog priority is not a single number but is, in
fact, the combination of a facility number and a severity. The
previous Go syslog implementation had a single Priority that
appeared to be the syslog severity and no way of setting the
facility. That meant that all syslog messages from Go
programs appeared to have a facility of 0 (LOG_KERN) which
meant they all appeared to come from the kernel.
Also, the 'prefix' was in fact the syslog tag (changed the
internal name for clarity as the term tag is more widely used)
and the timestamp and hostname values were missing from
messages.
With this change syslog messages are generated in the correct
format with facility and severity combined into a priority,
the timestamp in RFC3339 format, the hostname, the tag (with
the PID in [] appened) and the message.
The format is now:
<PRI>1 TIMESTAMP HOSTNAME TAG[PID]: MSG
The TIMESTAMP, HOSTNAME and PID fields are filled in
automatically by the package. The TAG and the MSG are supplied
by the user. This is what rsyslogd calls TraditionalFormat and
should be compatible with multiple systems.

Thanks to Dustin Sallings for exposing the most frustrating
bug ever, and for providing repro cases (which formed the
basis of the new tests in this CL), and to Dave Cheney and
Dmitry Vyukov for help debugging and fixing.
This CL depends on submited pollster CLs ffd1e075c260 (Unix)
and 14b544194509 (Windows), as well as unsubmitted 6852085.
Some operating systems (OpenBSD, NetBSD, ?) may still require
more pollster work, fixing races (Issue 4434 and
http://goo.gl/JXB6W).
Tested on linux-amd64 and darwin-amd64, both with GOMAXPROCS 1
and 4 (all combinations of which previously failed differently)
