Hmm, I think this can be very useful for other things.  Let's keep this
in mind to use in the future, even if we find another way to fix the
issue at hand.  In fact, I had a problem a couple of weeks ago in which
I needed two concurrent sessions and one of them disconnected in the
middle of the test.  Can't do that with isolationtester ...
