I like that idea very much.

You mean you're in essence creating a serial port server, right?.. Oh boy,
maybe there is hope for migrating NetBSD onto a Mach4 (or just plain Flex)
mk and run it single (UX) or multi server a la Mach_US, and solve all our
worries about multiprocessing at once...
Hey, I can dream, can't I?

Well, nah, you can implement the "port locking" functionality a la NeXT's
Mach drivers in NetBSD and go to a serial server architecture. The first
is redefining the functionality, the second is moving the actual handler
My guess is that you could very well implement it that way, without
conflict. Or am I missing something here?
