Since pfRealloc might choose to simply extend the existing memory
block (rather than allocating a new one and copying the data), it
is certain the pfRealloc can only use the same memory arena for
the reallocated block as was use for the block that needed to
be extended. Hence, there is no need for an 'arena' argument.
So, the short answer is: If the memory you are reallocating
is already in a shared memory arena - then so will the reallocated
memory. If the memory you are reallocating *isn't* in the shared
arena - then neither will the reallocated block.
AFAIK, there is no way to reallocate a non-shared memory block
into a shared memory arena without doing it yourself by doing
a pfMalloc and then a memcpy.
