Yes, but hardly anything that would allow us to do partial 
collections.
And without that you always have to scan the full live heap, this 
can't scale to bigger heaps, there is no way to scan a GB sized 
heap fast. So either we facilitate to get by with a small GC 
heap, i.e. more deterministic MM, or we spent a lot of time to 
make some partial collection algorithm work. Ideally we do both 
but the former is a simpler goal.

The connectivity based GC would be a realistic goal as well, only 
somewhat more complex than the precise GC. But it's unclear how 
well it will work for typical applications.
