	IIRC an AC_CLOSE message is sent before accessory termination. However for
pre-3.00 TOSes memory allocated "by the accessory" (in fact wrongly and
automatically associated by GEMDOS with the at-that-time active application)
may have been already unallocated... so on these TOSes the only way to cope
with this AFAIK is to patch the _p_run variable...
	Oh and I think (correct me please if I am wrong) that accessoiries never
get AP_TERM messages.
