If you can change the application, make it put stuff in:

/usr
  /htc
    /23
      /23702
        /primary
        /document
      /23703
        /primary
        /document
    /24
      /24001
        /primary
        /document

In other words, use the first two digits as an index into a superior
directory.  Then you'll have 1000 max entries in each level.  (1000
entries is still wayyy too much to search through, though.  Why are
you making the unix filesystem do the job of a database?)

If you can't change the application, throw it away.  That's a silly
mechanism (half :-).

Just another UNIX hacker,
