Today's changes.
More changes.
Pipes cannot use SOCK_DGRAM. Back to SOCK_STREAM.
Add debugging to fdwait. Rewrite getcallerpc on PowerMac to be correct.
Long-standing stability bugs fixed in 9pserve.
Update win to use acme interface directly instead of via pipes. Add comment to pipe about lack of message boundaries.
Fighting the good fight.
Move libfmt, libutf into subdirectories of lib9. Add poll-based socket i/o to libthread, so that we can avoid using multiple procs when possible, thus removing dependence on crappy pthreads implementations. Convert samterm, acme to the single-proc libthread. Bring libcomplete, acme up-to-date w.r.t. Plan 9 distribution.
Tweaks to various bits.
