That's an arguement for lkml.  But as I recall things, there shouldn't
be jitter, probably, with non multiples of 100.  There was some
discussion, and a fair bit of flaming about all of this on lkml.  I
think with some sort of numbers Linus might buy another choice added to
the list, but refuses anything "in theory" (this stems in part from the
must be 1000 crowd not being happy about 250 as the default).
