Q: What makes Morphic slow?

I know pretty much zip about the internals, but would it be possible to have
a blocking call that looks for a pen down, instead of checking an event
queue (which is what I assume is happening) in an event loop.

Good point! It never occured to me that the above would actually happen. Now
the question is what do we do?! Drain the batteries by disabling the delay?!
Any other suggestions?!
