I tried contacting Stephen the pool_allocator author, but his e-mail
is invalid (shouldn't the docs be updated?)

Here is what I wrote in case someone else here can offer some help:

I'm trying unsuccessfully to use your Boost::pool_alloc.  In the
documentation at the boost website:
http://www.boost.org/doc/libs/1_42_0/libs/pool/doc/interfaces.html
it says:

// Exiting the function does NOT free the system memory allocated by
the pool allocator
  // You must call
  //  boost::singleton_pool<boost::pool_allocator_tag,
sizeof(int)>::release_memory()
  // in order to force that

release_memory() does not seem to work.  Not sure why.  I called a
function in my code to verify my processes memory usage, and see that
indeed memory was not being released.  I also google searched and
found that others experienced the same:

Your help on this is requested.

Thanks.
