It could be a performance hit for slab with just one object - e.g the
page sized names cache, used in every syscall that has a path name as a
parameter.

Ed, have you benchmarked that there is no noticable slowdown?
e.g. test the time needed for stat("."). on UP, otherwise the SMP arrays
would perform the caching.
