The system process thing is to make sure the process terminates when all user
processes are done, but it doesn't prevent it from terminating earlier if it
wants to.

I don't think there's any misunderstanding, I'm just pointing out that the
right fix is to make winedevice exit and restart a new instance for the new
driver, instead of trying to restart the winedevice instance from inside
itself.

Calling the Unload function can certainly be done, though it's not clear that
it's actually necessary in any of the drivers I've seen. But things like
closing handles or freeing libraries just before exiting the process is a waste
of time.
