Description horowity@checkpoint.com 2011-05-24 10:59:04 UTC 
I have noticed that sort_hook function don't destroy temporary pool.

This leads to a memory consumption of ~500K (=68 hooks * 8K) per PROCESS!

The resolution is very simple - destroy this pool after usage (before returning the sorted hooks array).

Since the sorted hooks are memcpy'ed to another pool anyway, no one need this pool.
