---------------------------
sim: stopgap for race-conditions when using multiple EventQueues

This patch fixes several race conditions that appear in multi-
threaded mode. Currently the decode cache race condition is
fixed only for x86, and in a temporary non-optimal fashion. We
still need to decide on a more optimal solution for the decode
cache and apply it to all the ISAs.
