Subject: [PATCH] stress: prevent thread from holding write lock and then
 stopping

When a stress thread runs out of work, execute COMMIT and ignore
the result.

This prevents the currently extremely common scenario where:

- Thread x does BEGIN
- Thread x does e.g. INSERT ...

Then runs out of iterations and stops. No other threads can write
anything and they just wait for 5 seconds (busy timeout) and then
try again, forever.
