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.

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.

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.

The ARM code was inconsistent about whether the

#pragma dynexport is no longer needed for

It may still be necessary later.
On the Mac, you cannot use the GOT to resolve
symbols that exist in the current binary, so 6l and 8l
translate the GOT-loading mov instructions into lea
instructions.
On ELF systems, we could use the GOT for those
symbols, but for consistency 6l and 8l apply the
same translation.
The translation is sketchy in the extreme
(depending on the relocation being in a mov
instruction) but it verifies that the instruction
is a mov before rewriting it to lea.
