I just tried blanking a CD-RW with the latest -git tree. The

Does anyone have similar problems?
Instead of rebooting, just wait for the blanking to finish. My
guess is that your burner and hard drive are both on the same ide
channel, and so you can not access the disk while the burner is
blanking. If this is the case, put each drive on their own ide
channel.
It takes hard drive access to switch window focus? Yes, thats a
question.
Depends on your programs and RAM. If the program you try to switch
to (or, say, part of X or your window manage) is swapped out for some
reason, then yes, changing focus may cause said program to hang until
it can swap the data in. Usually that's a small fraction of a
second, but if your IDE bus is waiting for a burn, then it could be
the duration of the burn.
