*** 25,35 ****
       The Pclearsig() function instructs the system to clear any signal pending
       delivery to a thread in the process represented by the process handle P.
       The pending signal will never be delivered to process represented by P.
  
       The Lclearsig() function is identical to the Pclearsig() function, except
!      rather than operating on the process and its representive thread, it
       instead operates on the thread handle L.
  
       The Pclearsig() function only has meaning for active processes.  It will
       fail on process handles corresponding to core files, zombie processes and
       ELF objects.
