21    Defines PoolBase destructor
22    BLOCK START - PoolBase destructor, removes this object and possibly the
      whole vector
23    Initializes a local pointer to the global memory pool vector
24    Removes this pool instance from the global vector
25    If this is the last pool, remove the vector too

32    Defines PoolBase::Clean with one argument for the memory pool type
33    BLOCK START - PoolBase::Clean, calls type-specific Clean method for pools
      of matching types
34    Initializes a local pointer to the global memory pool vector
35    Initializes a local pointer to the last pool in memory
36    Begins a loop across the global memory pool vector of all types
37    Gets a local pointer to the current pool we're iterating over
38    If the types match -- call pool-specific CleanPool function
39    Redo loop until all pools tested
40    BLOCK END - PoolBase::Clean
