Comment (by simonmar):

 We already do that stability check. But recompilation of TH could be
 improved if we had a better idea of what the TH code actually depended on
 - when it's arbitrary I/O, we have to be necessarily conservative and
 assume that anything could change.  There's some design to do here to
 figure out what a better solution would look like.
