I always go nuts when I start an MTD test on a slow device and have to wait forever until it finishes. From the debug output I already know what the issue is but I have to wait or reset the board hard. Resetting is often not an option (remote access, you don't want lose the current state, etc...). The solution is easy, check for pending signals at key positions in the code. Using that one can even stop a test by pressing CTRL-C as insmod/modprobe have SIGINT pending.
