Continue switching library over to pthreads when possible.
Tprimes works on Linux 2.6. You can only have 128 procs though.
Rewrite to remove dependence on rendezvous and its bizarre
data structures. Makes it easier to use pthreads too. Still need to add code for non-pthreads systems. Just a checkpoint to switch work to another machine.
More consistent use of _exits and exits
in place of _exit and exit.
Small tweaks
Lots of new code imported.
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.
