Windows 7 Pro x64, RPC command "getwork" causes the rpc server to lock up, thread uses full CPU usage (25% on Q6600.)
Application has to be terminated via task manager.

No issue in 0.3.21, no other rpc commands seem to cause any problems, just "getwork"
First discovered problem by launching a local GPU miner (Phoenix), then verified it was the getwork command by testing with PHP client and just using the bitcoin command line.

Tested in a XP VM, same result.
