Bug Description

Currently there is no protection for scripts holding open transactions for a long time. Sometimes, this is hours.

We need timeouts such as the webapp has causing scripts to abort if they hold open a transaction longer than a configurable time limit.

We have seen recent operational issues related to this, so its critical : we will avoid various timeout OOPS if we do this. We need to be cautious about the deployment of it - needs to be easy to turn off because many scripts likely fail the test right now.

Oh, and I suggest an initial timeout of 20 seconds.

It might be nice to do this on jtv's recent script feature scope
stuff? Then it can be set dynamically per script.

We have a transaction killer today, but it (currently) isn't aggressive enough to solve this bug. Robert reports he envisioned per-script policies, because otherwise many scripts would fail today.
