Let me know when/if you use it. If you make changes to it, I'd like to learn
from your changes and the why of them.

Thanks. Don't have time to look at this now, but I did spend the time to
de-pool apr_hash
for use by mod_mem_cache (see modules/experimental/cache_hash.c). Some of
us are
interested in making mod_mem_cache work in shared mem so your code may do
the trick...

Subject: Modified apr_hash
> Hi guys,

use

> - my_shmem.c & my_shmem.h: child to child shared memory
> - my_shmem_hash.c & my_shmem_hash.h: hash table using my_shmem instead
of
