The test code used to do this:
for _, tc := range tests {
ch <- &tc
}
Note that &tc is always the same value here. As the value is
received from the channel, the sender can loop around and
change the contents of tc. This means that the receiver's
value is unstable and can change while it is in use.

Close of closed channel panics.
Receive from closed channel never panics,
even if done repeatedly.

There were duplicate closes and missing closes,
with the result that the program was rarely testing
as much as it seemed to be. Now it finishes.

Re-implement the debugging helper to be independent of the existing
implementation. This is preparatory to a rewrite to clean up issue 1416.
Include a definition of the grammar of the data stream.

This was broken after the last update (2011-01-20).
However, I'm not sure if the changed example is a
sensible use of import(), so I'd appreciate comments.

The functionality we want (shared ppid) is implied
by CLONE_THREAD already, and CLONE_PARENT
causes problems if the Go program is pid 1 (init).
See issue 1406 for more details.
Fixes#1406.

The o+i*p approach to visiting select cases in random
order stops being fair when there is some case that
is never ready. If that happens, then the case that follows
it in the order gets more chances than the others.
In general the only way to ensure fairness is to make
all permutations equally likely. I've done that by computing
one explicitly.
Makes the permutations correct for n >= 4 where
previously they were broken. For n > 12, there's not
enough randomness to do a perfect job but this should
still be much better than before.
Fixes#1425.

The default float type is not very useful but for the most basic applications.
For instance, as it is now, using the math package requires conversions for float
variables (the arguments for math functions are usually float64). Typical real
applications tend to specify the floating point precision required.
This proposal removes the predeclared types float and complex. Variable declarations
without type specification but with constant floating point or complex initializer
expressions will assume the type float64 or complex128 respectively.
The predeclared function cmplx is renamed to complex.

- added flag -maxresults (default: 10000) to limit the max.
number of full text results shown
- removed flag -fulltext; use -maxresults=0 to disable fulltext
index
- better indication on result page if not all results are shown

A query string of the form ident.ident will be used both as a qualified
identifier for identifier search and as a regular expression.
Qualified identifier lookup got broken accidentally when introducing
regexp full text search. Cleaned up surrounding logic a bit.

With the current implementation, xml unmarshalling
will silently fail to unmarshal any paths passing
through the same element, such as:
type T struct {
A string "dummy>a"
B string "dummy>b"
}
This change tweaks the algorithm so that this works
correctly.
Also, using paths that would cause the same element to
unmarshal twice will error out ahead of time explaining
the problem, rather than silently misbehaving.

When data is received for a channel, but that channel
is not ready to receive it, the central run() loop
is currently blocked, but this can lead to deadlock
and interference between independent channels.
This CL adds an explicit buffer size to netchan
channels (an API change) - the sender will not
send values until the buffer is non empty.
The protocol changes to send ids rather than channel names
because acks can still be sent after a channel is hung up,
we we need an identifier that can be ignored.
