Re: Very concurrent garbage collector for ARC

Well, this probably could be turned on/off using a environment variable (something like OBJC_CYCLE_GC)... but the point is that the overhead shouldn't be that big; Inferno's algorithm was projected to do really small steps each time, so that it wouldn't have to suddenly stop-the-world as most GCs.

I'm still testing the runtime overhead on GNUStep, but I believe that the overhead will be really small. I would probably be able to test the same thing for Apple's as well (if I manage to build it from source...).

I've been working on an implementation of a concurrent garbage collector (based on Inferno's,http://doc.cat-v.org/inferno/concurrent_gc/) to warn the user and reclaim memory in cycles found in ARC during runtime for the GNUStep's Objective-C library.

Is this as a debugging/performance tool? Or would it be incorporated in a released app? It sounds like a lot of runtime overhead to add, just to add the ability to free ref cycles.
