I think I've addressed this before, but the site that relies on being
able to roll back a set of updates is in my todo basket.

The current software holds the transaction over several actions, and
only if all can be completed does it commit. Moving this to PHP is
giving me a headache since up until now I've not had to do anything that
goes over a single page load. I can tag and undo easily enough, and THAT
may actually be better anyway since reserved stock will be flagged
earlier and can be retained even if an order can't be shipped due to
other shortages. But how do people handle holding a transaction open -
CAN we in PHP?
