As someone has mentioned, short-circuiting your queue means that queued
events are running at a lower priority than events that bypass the queue.
That is not necesssarily bad, but I find it undesireable. Adding a flag to
events such that if the flag is set, it bypasses the queue seems like a
better solution (ie marking some events "real-time").

In Moebius, our bottlenecks all seem to be in the interpreter, so in our
case, choosing the absolute best algorithms and data structures/models can
make all the difference in the world.
