+ * 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...
