APR memory allocation.
Resource allocation routines...
designed so that we don't have to keep track of EVERYTHING so that it can be explicitly freed later (a fundamentally unsound strategy --- particularly in the presence of die()).
Instead, we maintain pools, and allocate items (both memory and I/O handlers) from the pools --- currently there are two, one for per transaction info, and one for config info. When a transaction is over, we can delete everything in the per-transaction apr_pool_t without fear, and without thinking too hard about it either.
