Meant as illustration of the Go pattern that is using
goroutines and channels to handle exceptional situations.
Note: There is no need for "Finally" since the
"try block" (the function f supplied to Try)
cannot do a Smalltalk-style non-local return
and terminate the function surrounding Try.

Allows the developer to pass a map either by itself for
evaluation, or inside a struct. Access to data inside
maps is identical to the current system for structs, ie.
-Psuedocode-
mp map[string]string = {
"header" : "A fantastic header!",
"footer" : "A not-so-fantastic footer!",
}
template.Execute(mp)
...can be accessed using {header} and {footer} in
the template. Similarly, for maps inside structs:
type s struct {
mp map[string]string,
}
s1 = new s
s1.mp["header"] = "A fantastic header!";
template.Execute(s1)
...is accessed using {mp.header}. Multi-maps, ie.
map[string](map[string]string) and maps of structs
containing more maps are unsupported, but then, I'm
not even sure if that's supported by the language.
Map elements can be of any type that can be written
by the formatters. Keys should really only be strings.

Previously a netFd could be queued for reading/writing in the channel,
but close(2)'ed before pollServer got to it. In this case, the kernel
would consider the descriptor closed and the attempt to add it to the
epoll set would fail and panic.
This patch makes Close a roundtrip to the pollServer, although the
actual close(2) still occurs elsewhere to avoid blocking the
pollServer.

Error information is carried from RPC server to client in the string
'Error' field of rpc.Response. An empty string is sent in the success
case. This empty string was being returned to the caller (of Client.Call
or Client.Go), resulting in a non-nil error response.
This change detects an empty-string Response.Error at the client, and
translates it into a nil value in Call.Error.
Tests updated to check error return in success cases.

This commit simplify setinclude(), by removing the special case

We are dealing with the multiplicative group ℤ/pqℤ. Multiples of
either p or q are not members of the group since they cannot have an
inverse. (Such numbers are 0 in the subgroup ℤ/pℤ.)
With p and q of typical size (> 512 bits), the probability of a random
blind [1..pq-1] being a multiple of p or q is negligible. However, in
the unit tests, much smaller sizes are used and the event could occur.
This change checks the result of the ext GCD and deals with this case.
It also increases the size of p and q in the unit test as a large
number of the keys selected were p, q = 227,169.

The default SELinux policy on Fedora 12 (at least) disallows stack
pages to be +x. This causes all binaries written by 6g/6l to segfault
immedately. The 'true' way to fix this issue is to mark binaries with
the correct type. However, that assumes that 6l is going to detect
SELinux, figure out the correct type for the current distribution and
set the type (without libselinux).
For now we'll warn users and point them towards the way to enable
execstack for the whole system.

- When providing alternative spellings to a query, do not
prefix it with a package qualifier as the suggestion may
not have any results. Correctly filtering is quite a bit
of work, and clicking the alternative spelling will always
also show the qualified hits if they exist (but also others).
Seems good enough for now.
- Give user feedback when the query syntax was wrong.
- Package names in search results are now links to the respective
package documentation.
- Experimented with excluding main packages and test files
from index with inconclusive results. Code is present and
can be enabled by changing a flag in the source. This needs
