410  bad applications hung but not aborted. Currently it is not a problem for Linux* OS, OS X* and
411  Windows* OS.
412 
413  Grant: Found new hangs for EL4, EL5, and a Fedora Core machine. So I'm putting
414  the default back for now to see if that fixes hangs on those machines.
415 
416  2010-04013 Lev: It was a bug in Fortran RTL. Fortran RTL prints a kind of stack backtrace
417  when program is aborting, but the code is not signal-safe. When multiple signals raised at
418  the same time (which occurs in dynamic negative tests because all the worker threads detects
419  the same error), Fortran RTL may hang. The bug finally fixed in Fortran RTL library provided
420  by Steve R., and will be available soon.
