How many files can there be in a single UNIX directory
(I realize this may depend on the variety of UNIX; I expect
the Berkeley fast file system would allow more)?  I need
a better answer than "a lot" or "at least 2000", if possible.

(This concerns an application program we are currently running
on an Apollo under Aegis; it depends on a LOT of files being
in a single directory and Aegis's limit of 1500 or so can
be a pain.)

I realize that as directories get bigger, they slow down, but
how much?  Just what IS the maximum directory size?
