Thanks for the response. I am reviewing the boost.pool reference here:
http://www.boost.org/doc/libs/1_49_0/libs/pool/doc/html/boost/pool.html

Based on that, I do not see a way to allocate blocks of varying sizes. The
documentation makes it sound like I have to set size_type to the largest
object that will be allocated, which I have no reasonable way of knowing (I
have hundreds of objects in my inheritance hierarchy, each with varying
size, and no way to calculate the largest in a maintainable way).

The malloc() method does not take any parameters.

Am I misunderstanding you? Could you please point me in the right
direction? Thanks again for your help.
