	I an not an expert; however, based on material reported here:
	In terms of perforance, ULE and BSD are equivalent on UP
machines - BSD works better in some cases, ULE in others.  If I had
to put money down, I'd give a very slight advantage to ULE.
	Measured by stability, ULE is a moderate win.
	Absent specific cases to the contrary, one reason to go with
ULE is that it where future development is focused.  That's not to
say BSD is being kicked off the train, exactly, just that it won't
be the target for the latest and greatest.

	More qualified voices will please tell what I have remembered
