I can see different hooks being useful: initialization of memory to
user-defined values, reports of memory usage, memory leaks, etc.

There are several guidelines I'd like to place down now for any such
changes:
  1) There should be *no* penalty for not using them
  2) The user interface should be changed minimally, and should not become
overly-complicated

It may be possible to add a single optional template parameter, which would
supply any necessary debugging/statistical functionality.  Just don't add
each debugging flag as a separate template parameter to sized_pool; invent a
"debugging traits" class instead.
