I can’t make any sense out of your equivalency assertion. GC won’t magically reclaim memory that is still referenced; there still comes a point where if you can

  > GC won’t magically reclaim memory that is still referenced I never said it would. What I said that making GC hard-real-time is no more difficult than making malloc/free hard-real-time. You can do manual memory management in a GC'd system. If you do that, the two systems are literally the same. The only difference between GC and manual memory management is that in a GC'd system, unreferenced memory will eventually be reclaimed and in a manual system it won't. If you lose all references to an allocated block in a manual system, it's gone forever, whereas in a GC'd system you can get it back. This enables a programming style that puts less burden on the coder to prevent memory leaks. But none of this has anything to do with being hard-real-time. Hard-real-time is hard, period, end of story. GC is completely orthogonal to this. Hard-real-time is hard in a GC'd system and it is exactly as hard in a non-GC'd system. The only difference between the two is the same in both hard-real-time and non-hard-real-time cases: in a non-GC'd system, the coder has an extra burden to write code that doesn't leak. That's it.
