I don't know exactly what the person wants to do with stats from /tmp,
I had some mail from him, but it wasn't totally clear what sorts of
stats he wanted, but I want to point out that not all files in /tmp
have names. A neat trick to avoid leaving /tmp files around when
a program crashes is to do this at creation time.

	fd = creat(name, mode);	/* or open with O_CREAT */
	unlink(name);

Now the file is nameless and can only be accessed via the fd. It
will go away as soon as nobody is referencing it.
