Chris,

I'm trying to catch up here after hacking on the reactor implementation in
a corner for a few days.  Could you point me to a post that describes the
custom memory allocation interface?

One thing I've done is written a pooled_list implementation and
parametrized the list implementation used by your hash_map.  This
eliminates a bunch of hits to the global allocator, at the cost of a
pre-allocated fixed hash_map size.  Considering that the hash_map
associates FDs with handlers, I think this is a reasonable trade off.
