virtual bool OnExceedLimit(MemoryHeap* heap, UPInt overLimit) = 0;
OnExceedLimit is called when the limit on memory as set in HeapDesc is reached and the handler tries to free memory of at least "overLimit" size in summary (release cached elements, invoke GC, etc). If freeing is not possible or there is not enough size of elements, the method can increase the memory limit by calling SetLimit. In both these cases, the method should return true. If neither is possible, the method returns false and the allocation call fails (returns 0).
