Clark and Roland McGrath: http://www-static.cc.gatech.edu/~shivers/papers/heap.ps presents several *neat* hacks to do this efficiently. I'm sure that the implementators on the list are already aware of this work, but I just wanted to point it out as interesting reading for people (like myself) who think this stuff is neat but don't necessarily have broad experience with it.
