Subject: [PATCH] fix bug in previous - if child was traced and p_opptr ==
 p_pptr, need to reparent the process to initproc, so that child wouldn't have
 its p_pptr pointer still pointing on the exited parent

pointed out by Dave Sainty in private mail (the patch in kern/14443
didn't have this bug)
