	I heard 10k a while back from several sources I considered reliable.
I've always stuck to that limit and never had a problem on freebsd or
sun. I've also had very good luck with a hashed directory structure,
such as: 

/a/b/c/abcfile

The level of hashing, and the number of characters per level can be
determined by your expected number of files, naming schemes, etc.

Good luck,

Doug
