In one of these articles, they describe an interface that allows a heap
monitor to be hooked in which a running application in MS's JVM.
Pretty neat. It allows your to extract all kinds of roots, traverse the
heap, be notified when objects are allocated, etc. basically to completely
monitor the heap.

Providing such hooks would be a potential added value for Kaffe in the
future. I don't think Sun has already defined an API for that, though
I'm not positive about that.
They do have an API to access some heap management functions, but not
the monitoring MS is doing.
