  Log:
  Fixes for signal handling:
  
    o Don't call signal handlers with the signal handler access lock
      held.
    o Remove pending signals before calling signal handlers.  If
      pending signals were not removed prior to handling them,
      invocation of the handler could cause the handler to be
      called more than once for the same signal.  Found by: JB
    o When SIGCHLD arrives, wake up all threads in PS_WAIT_WAIT
      (wait4).
