So, this might be an issue outside of revisor, but:

When composing live images, all of my input locks (on all applications). For example, I can't type in this inputbox off and on while running the yum transaction in the chroot. Also, I can't type in xchat. Strangely, only one of my cores is in use and beryl runs fine, I can start applications, etc, but am unable to input any data. Mouse works fine, it's strange. Maybe it has something to do with a callback that is runaway?
