422  Signal handling is disabled by default, because it confuses users: In case of sigsegv
423  (or other trouble) in user code signal handler catches the signal, which then "appears" in
424  the monitor thread (when the monitor executes raise() function). Users see signal in the
425  monitor thread and blame OpenMP RTL.
426 
427  Grant said signal handling required on some older OSes (Irix?) supported by KAI, because
428  bad applications hung but not aborted. Currently it is not a problem for Linux* OS, OS X* and
429  Windows* OS.
430 
431  Grant: Found new hangs for EL4, EL5, and a Fedora Core machine. So I'm putting
432  the default back for now to see if that fixes hangs on those machines.
433 
434  2010-04013 Lev: It was a bug in Fortran RTL. Fortran RTL prints a kind of stack backtrace
435  when program is aborting, but the code is not signal-safe. When multiple signals raised at
436  the same time (which occurs in dynamic negative tests because all the worker threads detects
437  the same error), Fortran RTL may hang. The bug finally fixed in Fortran RTL library provided
438  by Steve R., and will be available soon.
