Any transaction monitor need resource registration and transaction
creation facilitities.  This is quite different from the concept of
P5EE sessions, which is a stateful bit bucket which resides outside a
particular transaction resource.

P5EE should initially rely on the database's transaction monitor and
expand as the problem space requires it.  In bOP, we have a simple
mechanism to register transaction resources with a request object,
which for now, does not implement two phase commit.  It is sufficient,
because transactions aren't distributed.  However we do need to be
able to rollback pending e-mail messages, locks, and other ephemeral
request resources should the request fail.
