Threads are arranged into procs.  Threads within
a proc are scheduled cooperatively whereas the procs
are scheduled preemptively by the Plan 9 scheduler.
Threadcreate makes a new thread in the same proc
as the calling thread.  Proccreate makes a new
proc and starts a new thread running in it.

The thread(2) man page describes this.  For more information
on threads and procs see the Alef User's Guide, linked at
http://plan9.bell-labs.com/~rsc/thread.html#8
