Don't require INTR_FAST handlers to be exclusive in the MI layer.  Instead, let the MD code choose whether or not to implement such a policy.  The new i386 interrupt code allows multiple FAST handlers for a given source for example.  However, the code does not allow FAST and non-FAST handlers to be mixed.
