Have you run out of punctuation marks at your company? -- They surely help

But sure, if you can't take memory leaks, then garbage must somehow be
collected.

I use C++ which does that cleanup automatically (if all used memory
management is wrapped up in automatic objects). So I do not know.

But I am not GNU, just a reader of this list. -- Perhaps somebody else can
give a better answer.
