FWIW, that is one of those archetypical problems that crops up in event
driven software. It is a sure sign that an event has gone missing or is
being ignored. Events can be interrupts, or data appearing on an
interface that is polled. In this case it would probably have to do with
emulated hardware.

Just a general comment, but maybe it will jog something loose for the
right person...
