It's based on ideas mainly borrowed from jemalloc and tcmalloc. I hope, the patch must implement all the features of previous memory manager except for "overridable storage", but I might miss something. It would be great if experienced people could analyze the sources and give their opinion. Thanks. Dmitry. --485b397dd5e5ca4bd50500e62cf6--
