I've been wondering if trunk code would show these deadlocks.... I have some
improved code in a jira and occasionally it also seems to show this problem.
(I've personally never seen it locally, it shows up occasionally in automated
builds at work) I've added some more stuff that ought to log appropriate info
when this occurs, so since this has shown up "in the wild" I'm very tempted to
commit the improved code and the (probably temporary) extra logging.
Any objections?
thanks
