Not afaik. Yeah it's not super-fast, for some reason. It's been fast
enough for me, I don't know where the bottleneck is. It can be useful
for some things, but obviously there are cases where debugprints are better.

(One cool feature is ".kdfiles" -- you can have it load the driver
you're working on from your dev machine. This removes the need to reboot
simply to copy a new version of the driver over.)

Don't know, haven't used.
