When transmission checks existing data for torrents with large files, the entire OS becomes unresponsive until the checking is done. I can't even move focus to a running terminal to grab any i/o numbers. There's a ticket to improve responsiveness of transmission itself during checking, but that won't help the OS. Is there a way for the data check to lower it's priority so it doesn't affect the entire OS?
OS: Snow leopard
Transmission: svn r10107
