	4DOS is loading it's transient part (~60k) the first time you time DIR.  On
my 12 MHz AT clone, it takes < 1 sec (definitely never 2 sec) to do this from
RAM disk in extended memory.  I'd have thought it would be similar or faster
from expanded memory.  It actually seems only a tad slower if I swap from the
hard disc.
