The problem was that if an instruction ended up on the worklist more than once,
it would get deleted more than once.  Whoops.

Bugfix here:

I merged this to the 1.1 branch because it is an obvious (safe) fix and an
obvious problem that could effect a lot of people.  I hope this is ok.  :)  If
not, the patch can be reverted.
