As for AAs, you should be able to replace them with Tango's 
tango.util.container.HashMap with the 
tango.util.container.Container.Container.Malloc (or .Chunk) allocator.

It might be tricky to find memory leaks due to accidental GC usage, but 
you could e.g. hook the GC methods ( http://dsource.org/projects/kong ) 
(or modify the GC) and print stack traces in them.
