From df9f99567d43c9dfcecc625dce748c561699b307 Mon Sep 17 00:00:00 2001

Subject: [PATCH] pseudoinst: get rid of mainEventQueue references. Avoid
 direct references to mainEventQueue in pseudo-insts by indirecting through
 associated CPU object. Made exitSimLoop() more flexible to enable some of
 these.
