But only if the thread has low memory footprint. The downside of 
a fast scan is that it may wipe out all caches, thus slowing down 
nongc threads.

To combat that you either need memory barriers to get incremental 
collection, which most likely require a language change, or you 
can only collect very slowly.

So well, ARC.
