interesting limitation

[NOLL Janos]

Hi!

 Yes, and ext2/3 has the same limitation.
 Ext2/3 code in the Linux kernel can be modified (one line) and
recompiled to allow more directories, up to cca. 65000.

 ReiserFS is known not to have this limitation, if I'm right.

 But the solution should be a (configurable) more scalable hashing
method, for a large user base.
