  Added files:
    devel/pth/files      patch-aa 
  Log:
  This patch fixes a scheduling bug and is to be incorporated in the
  next version. In the meantime, apply with the port.
  
  FYI, the bug is demonstrated by this program:
  
  #include <stdio.h>
  #include <stdlib.h>
  #include <pth.h>
  static int check_something(void *arg)
  {
          return (0);
  }
  static void *thread(void *arg)
  {
          printf("thread sleeping five seconds...\n");
          pth_nap(pth_time(5, 0));
          printf("thread is done sleeping\n");	/* bug: we never get here */
          return (NULL);
  }
  int main(int ac, char **av)
  {
          pth_event_t ev;
          pth_init();
          pth_spawn(NULL, thread, NULL);
          ev = pth_event(PTH_EVENT_FUNC, check_something, NULL, pth_time(2, 0));
          while (1)
                  pth_wait(ev);
  }
