> If your technical (theoretical) definitions are useless, you need to use different definitions... The question of "what is a real-time GC" is academic because nobody actually wants a real-time GC. They want a real-time system. And some GC algorithms can be used to construct a real-time system. Indeed, as others have noted, SBCL can be used to construct a real-time system if you don't do any allocations.
