   sigsegv (or other trouble) in user code signal handler catches the signal,
   which then "appears" in the monitor thread (when the monitor executes raise()
   function). Users see signal in the monitor thread and blame OpenMP RTL.

   Grant said signal handling required on some older OSes (Irix?) supported by
   KAI, because bad applications hung but not aborted. Currently it is not a
   problem for Linux* OS, OS X* and Windows* OS.

   Grant: Found new hangs for EL4, EL5, and a Fedora Core machine.  So I'm
   putting the default back for now to see if that fixes hangs on those
   machines.

   2010-04013 Lev: It was a bug in Fortran RTL. Fortran RTL prints a kind of
   stack backtrace when program is aborting, but the code is not signal-safe.
   When multiple signals raised at the same time (which occurs in dynamic
   negative tests because all the worker threads detects the same error),
   Fortran RTL may hang. The bug finally fixed in Fortran RTL library provided
   by Steve R., and will be available soon. */
