A difference, I think.	4dos appears to do 100 deletes, where
command.com invokes some of the DOS magic dust and just kills the
directory entries and frees all the clusters en masse.	That, though, is
the _only_ point on which command.com can win against 4dos.

Things could be worse; you could be doing 100 deletes through the
NewSpace compressing disk driver... at about 2-3 deletes per second.
