[ITP] pth-2.0.1-1, GNU Portable Threads

["Gerrit P. Haase" <gp at familiehaase dot de>]

Hello,

I want to contribute and maintain pth, the GNU Portable Threads.

It builds without modifications since version 1.4 but I never got it
managed to get a shared library, finally I succeeded now to build it
with a DLL.  All tests are passing.

sdesc: "GNU portable threads."
ldesc: "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 (aka `multithreading'') inside event-driven applications. All
threads run in the same address space of the server application, but each
thread has it's own individual program-counter, run-time stack, signal mask
and errno variable.

The thread scheduling itself is done in a cooperative way, i.e., the
threads are managed by a priority- and event-based non-preemptive
scheduler. The intention is that this way one can achieve better
portability and run-time performance than with preemptive scheduling.
The event facility allows threads to wait until various types of events
occur, including pending I/O on filedescriptors, asynchronous signals,
elapsed timers, pending I/O on message ports, thread and process
termination, and even customized callback functions.

Additionally Pth provides an optional emulation API for POSIX.1c threads
(Pthreads) which can be used for backward compatibility to existing
multithreaded applications."
