I'm quite sure it uses a lot of reallocmem's and FPC's hepmanager is
currently very bad at compacting the heap (so most of the time we have to
allocate a new block when someone does a realloc mem and we end up with a
lot of small, often even contiguous, blocks which are never concatenated).

Concatenating when allocating instead of when freeing would help here, but
it would probably slow down the heap manager in cases where this wouldn't
be necessary otherwise.
