Well aren't I good! 
I think I've written a really useful tool for visualizing the memory usage. It reads a memdump.xml file produced by the "dumpmem" console command, and outputs a list of functions and total memory they and their children allocated, as well as a DOT file for drawing a graph (using GraphViz) representing the hierarchy of memory allocation.
Have a look here: http://mc-server.xoft.cz/img/memdump.svg (you need a decent browser, it's a huge picture in SVG format, 1 MiB in size; scroll to the center to find the actual image data)
And the list (example extract of a 54 KiB text file):
Now I only need the memory allocation data. And I think I'll add some filtering, having CryptoPP and Lua in that graph is pretty useless.
I'll now write the code to dump memory when memory usage reaches 1 GiB.
