For more complicated applications this is only possible with locking. Does
Zope provide locking primitives?

Or, ideally, something like asynchronous message passing? I would love to be able to start a transaction and, if it finishes in less than x seconds, tell the user the result or, if it hasn't finshed by then, that the transaction is
being processed, please come back later.

If you are interested in async programming with zope have a look at twisted, here's some info:
