Well, if no pointer exists to an object, there's no way somebody can use it. It seems you don't know what you're talking about.

Fragmentation only exists in languages which don't support GC well (i.e., C). GC have been able to fix that for ages. Whether we have decent heuristics for handling it without using too much CPUs is an open issue, when that's a problem choosing the GC algorithm among the implemented ones is the best solution.
