It's was actually way easier than I thought.

I thought you could not do this because if it's an IE command, and IE is taken,
you would wait for it.

Well, I was kind of stupid. It's save to put it into the front of the queue if
we actually made some progress (for example if we did run a compilation
command). But if we dequeue it from the front and there is no slot available we
HAVE to put it on the end. (which is on line 1620).
