    Since my application needs inter-process locking which won't
    be available through Pthreads/POSIX semaphores until Linux
    2.5, I've added a SysV semaphore set manager to my app and it
    is running beautifully now.

    Yes, Pth also segfaults with the posted test case on Linux.

    It's great how the next-generation development effort has
    benefitted from State-Threads.  Through on-going refinement,
    the original simple design has been extended to a much more
    complex one.  The State-Threads package has enabled me to
    make tiny steps between each evolutionary change, so that I
    could validate each step.

    Mike, thank you for State-Threads.
