The GNU Portable Threads
 Pth is a very portable POSIX/ANSI-C based library for Unix
 platforms which provides non-preemptive priority-based
 scheduling for multiple threads of execution ("multithreading")
 inside server applications. All threads run in the same address
 space of the server application, but each thread has its own
 individual program-counter, run-time stack, signal mask and
 errno variable.
