No - I went through your patches in some detail, but I didn't see one 
that addressed this problem specifically. Once thundering herd is 
solved, I plan to commit all your refactoring patches.

I didn't like that sleep/fstat hackery. How about using a real file
notification scheme ?

The prerequisite is that APR needs to be taught about this scheme, and 
it has to work portably across all platforms.

No it doesn't.  mod_disk_cache makes many assumptions about the 
underlying OS, like how moving a file on the same file system is atomic, 
and how you can move files that have open file descriptors, both of 
which aren't true with some file systems or operating systems (like uh.. 
windows).

mod_disk_cache is a high performance part, lets make it work great on 
most unixy/POSIX type platforms, and come back to making it portable later.
