No, pth provides non-preemptive threads. If you need preemptive threads then
use POSIX threads (which are available on any modern Unix variant.)
Non-preemptive threads are great for things like discrete event simulations
(or any other application where threads make sense but preemption isn't
necessary.) One simple simulation I ran took over 2 minutes to run using
POSIX threads. Most of this time was spent just switching between threads.
The same simulation converted to use pth took only 8 seconds to run.
