 * Define this to use signals for MPCI shared memory driver.

 *
 * BEWARE:: many UN*X kernels and debuggers become severely confused when
 *          debugging programs which use signals.  The problem is *much*
 *          worse when using multiple signals, since ptrace(2) tends to
 *          drop all signals except 1 in the case of multiples.
 *          On hpux9, this problem was so bad, we couldn't use interrupts
 *          with the shared memory driver if we ever hoped to debug
 *          RTEMS programs.
 *          Maybe systems that use /proc don't have this problem...
