Subject: libgo patch committed: Fix race condition in netchan test

This patch, copied from the master Go library, avoids a race condition
in the netchan test.  The consequence of the race condition would
normally be a deadlock.  Bootstrapped and ran Go testsuite on
x86_64-unknown-linux-gnu.  Committed to mainline.
