Right, it's not directly related to the deadlock. I mentioned it on that thread because we are now able to test with trunk on the MCS servers.

I'll take a look at other commits around that time and see if there is anything else.

Automated tests have been running nightly for a few weeks now on 0.93 and trunk.

http://www.ci.uchicago.edu/swift/wwwdev/tests/tests.pl

I will add automatic provider testing to that soon, and clean up the organization a bit.
