gah. I've said this before, but I /hate/ intermediate waits. if something happens in like 0-4 seconds, that's great. I can just focus on it. if something takes an hour to run, that's fine too, because I can do other stuff in the background.
but things that take like 20 seconds to 2 minutes are the worst, because they're just long enough for me to task-switch away, but not so long that it makes sense to have a notification system to tell me when they're done
