Well, there is a general-purpose pooled allocator already. It's called the heap
manager ;-)

Jokes aside, I did a bunch of counting. The only thing that sticks around are
50kB TLazIntfImage instances. Everything else gets freed right after processing.
Just from the order of alloc/frees, there shouldn't even be gaps, so I would
expect the next iteration to just find those allocations to be empty and reuse
them. But for some reason, that doesn't happen.

I've compiled with FastMM for now, but it turns out this is in fact a bit slower
than the RTL MM, and I don't really trust my port yet...
