Warning -- Apache can't repeal the laws of physics either. It still has
to do directory lookups just like IC does.

You will be much happier if you hash your directories (like IC does with
the session directory) and keep maximum entries down to a thousand or less.

If you have a lightly loaded server with plenty of available I/O bandwidth,
you may get away with it. But it would be the first place I look should
you have performance problems.
