Fascinating. I look forward to the coverage of Jemalloc!<p>On a related note, I'd love to use (or see someone else use) some of the techniques used by modern mallocs (tcmalloc, jemalloc, Hoard, etc) in a concurrent garbage collector. I believe the Boehm GC already uses thread-local free lists, but in an accurate GC, i'd bet more tricks could be put to use
