I've checked the urweb-callback against the new version of the UrWeb.
Unfortunately, urweb-callback fails to pass the stress test with your
version of uw_commit. The symptom is a 'job leak' - several jobs are
not freed at the end of the test. At first glance your version is
quite similar to mine, but probably there is a critical difference
hiding somewhere.  I'll try to figure out what is going on.
