Bug 308235

Description Remy Suen 2010-04-06 12:46:09 EDT

Don't remember what I was doing. It just decided to hang. John suggested some renegade code may have forgotten to do an unlock, maybe in a 'finally' block or something.

I'm using an e4 SDK build from last night which is based on I20100330-0800.
