I think t.insertObject(c) isn't a good idea.  Client(1) is an object
that may be in use in several places, and is presumed to be
transparently persistent.  When you put it into the transaction you've
made temporary for all users of the object.  Bad bugs will follow.  At
least in threaded situations.

This is why I think the object has to be instantiated as part of the
transaction, or perhaps copied if you don't like instantiation...

t = Transaction()
c = Client(1)
ctmp = c.inTransaction(t)
# or...
ctmp = Client(1, t)
