But that's not true at all.  And I'll be glad to fix up anything, I just
need to make sure that the system still will work properly when doing
so.

thanks.

Heh, so do I.

And this is an odd "driver", I do know that.

But it solves a real problem that can't be solved any other way
currently, which is needed for a real system that is shipping.  So, if
it can't be solved any other way, do you have a way this kind of thing
could be more "correct"?
