Just an FYI, and I don't really care too much. But my personal
preference, is to only join variables that are being used the same way.
That is, multiple file descriptors sure:

	int sfd, s, cfd;

But I prefer to keep file descriptors separate from pid.

	int cfd;
	int pid;

But as I said, this is only a preference and I don't really care that
much about it to even bother to change the patch.
