Commitment Control really shouldn't require persistence.  I
know Net.Data does it without it.

Since the "actions" happen on one request, I would think
this is where you would commit or not.

This is just me, but I don't use Commitment Control or
persistence for more than one reason that I don't think we
want to start another holy war on.  :)
