----------------
After thinking about this a little more, I think this comment is misplaced.  I believe the cleanup code will always precede the catch code if they are in the same block, and the cleanup handler will stop cloning when it sees eh.begincatch.  The cleanup code may be duplicated in the catch handler.

In any event, I'm going to delete this FIXME comment and see if I can create a test case.
