I created the dry-run mode to be able to easily generate the set of
possible permutations for a new test, then edit the result and put it
back in the spec file; but after the deadlock tests were added (with
necessary hacking of the lock-detection in isolationtester) that manner
of operation became almost completely useless. Maybe we need to rethink
what facilities isolationtester offers -- possibly making dry-run have a
completely different behavior than currently, which I doubt anybody is
using.

All that being said, I have no objections to this patch (but I didn't
review it closely).
