                          thr_spinlock.c 
  Log:
  Don't really spin on a spinlock; silently convert it to the same
  low-level lock used by the libpthread implementation.  In the
  future, we'll eliminate spinlocks from libc but that will wait
  until after 5.1-release.
  
  Don't call an application signal handler if the handler is
  the same as the library-installed handler.  This seems to
  be possible after a fork and is the cause of konsole hangs.
