--- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-12-24 14:37:23 UTC --- I don't have a strong opinion, but it's a bit hard to make a choice: the legacy HP/SGI pool still makes sense; mt too, has some problems, but we spent quite a bit of time on it, works decently well in a few circumstances (still, I have to tell Pawel, enabling it as default allocator isn't something one should do with light heart); bitmap I would not include, actually I would deprecate and remove it completely, you know that already.
