Re: [xml] Memory not going away..

In broad handwaving terms, once a process allocates memory, that memory does not go back to the system until the process terminates. Malloc will call brk, but free will not try to give it back to the kernel, it will keep it in the process on the chance that the process will want memory again.

That is not to say that an OS/runtime might choose to have a way to give the memory back to the kernel before the process terminates. Not clear how many actually do or if it would be a win.

Either mechanism can be considered "correct."
