Well, yes -- you want to know that the server can be reset and return
to the initial configuration with no lingering effects from the
previous session.

Yes, there's no reason to involve the DDX in the reset process; we
just need to make sure the server returns to the initial state at
reset time as seen through the protocol.

Reset was extended to involve the driver back in the R3(4?) time frame
so that memory leaks and other such things could be more easily
detected -- resetting everything left the number of objects allocated
very small at one point in the process, and we could hand-audit the
remaining objects to ensure that none of them were leaks.
