- * Define this to use signals for MPCI shared memory driver.
- * If undefined, the shared memory driver will poll from the
- * clock interrupt.
- * Ref: ../shmsupp/getcfg.c
- *
- * 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...
