Yeah, but the problem is that the loaded driver is trying to call an
internal routine, and instead is accidentally calling *back* to the
driver manager. I would guess that for every call made to the loaded
driver, the driver manager is not expecting any more of its code to
execute until control returns from the loaded driver routine.

Yup.
