Some of the hits point at commercial tools, which you didn't mention. I've heard positive comments about YourKit in the past. It is commercial, but it looks pretty easy to get a 15-day evaluation license. I haven't used it, but it claims to have some features to aid in detecting and analyzing memory leaks: http://www.yourkit.com/docs/80/help/memory_leaks.jsp
I also saw hits for a tool called plumbr. I have no information about it, good or bad.
