Can somebody please time the current stdio functions on different setups
(local vs networked drives, compressed vs uncompressed drives, disk cache
vs vanilla DOS, etc.) and see if such a change will indeed make it
significantly faster?  I'm worried about making a change that will
complicate the code without knowing what we'd get in return.  The
explanation that Alexander gave makes a lot of sense to me, but I have
seen too many cases where an obvious explanation has proven to be wrong.
