BTW: I used this stuff about 20 years ago: http://www.microquill.com/ and they are still around. And yes, it was damn fast and HeapAgent was a great tool to use. -- Robert M.

Really we ought to use Boehm, as the newer versions can be generational Not really you can’t - first check the API to understand that without manually placed (or injected by compiler) safepoints it doesn’t work. It is potentially quite a lot better than our version of it. It might be.
