	I need to do fast i/o (especially writes) to disk from/to a network
	peripheral.  What is the best way to do this?  (System=ISC/Sunsoft
	System V.3).  For performance reasons I think I want to do this in a
	driver, but I don't know how to get to the disk "legally".  The access
	to the network devices is (depending on device) via DMA or shared (low)
	memory.

	It doesn't really matter if the data on disk isn't accessible via the
	filesystem, but it wouldn't hurt.  I assume I don't really want to go
	through the buffer cache (again for performance reasons) but I could be
	wrong.

	Killing performance for the system users is not a big problem, but I
	don't want to lose interrupts, etc.

Thanks for any hints,
Eric
