468  sigsegv (or other trouble) in user code signal handler catches the signal,
469  which then "appears" in the monitor thread (when the monitor executes raise()
470  function). Users see signal in the monitor thread and blame OpenMP RTL.
471 
472  Grant said signal handling required on some older OSes (Irix?) supported by
473  KAI, because bad applications hung but not aborted. Currently it is not a
474  problem for Linux* OS, OS X* and Windows* OS.
475 
476  Grant: Found new hangs for EL4, EL5, and a Fedora Core machine. So I'm
477  putting the default back for now to see if that fixes hangs on those
478  machines.
479 
480  2010-04013 Lev: It was a bug in Fortran RTL. Fortran RTL prints a kind of
481  stack backtrace when program is aborting, but the code is not signal-safe.
482  When multiple signals raised at the same time (which occurs in dynamic
483  negative tests because all the worker threads detects the same error),
484  Fortran RTL may hang. The bug finally fixed in Fortran RTL library provided
485  by Steve R., and will be available soon. */
