It basically wipes out the benefit entirely.  If you feel that this
approach is risky, I'd prefer to skip the patch entirely.  We'll need
something like this in some unrelated series I'm working on.  Perhaps
it can go in then.  After all this is just a temporary measure until
the *correct* way to solve the problem appears. I.E. separate flow
miss handling into it's own thread so these real time concerns stop
being an issue. Thoughts?
