Thanks Andy I will look at them shortly.

I can clean up the unit test we used for the cancellation
case, it's fast but it only shows that closing the QueryIterSort
iterator closes the source iterator to -- I've been wondering
how to do an integration test that shows that the "didn't close"
warnings have gone away.

I will construct a test for the regex changes.
