This pooling introduces severe lock contention for Liftoff compilation,
since each compilation uses its own Zone which does at least one
segment allocation.
It's also unclear whether pooling improves performance, since {malloc}
should implement a similar pooling mechanism, but better optimized for
multithreaded uses.
Feel free to revert if this introduces significant regressions.
