What’s the problem with allocating them as they’re used? If I never use System V IPC, why should I have to burn a page of RAM on them? > Do you object for all ports, or just smallish ones?

If you apply this “well, it’s only a page” attitude across N different things, pretty soon you’re talking about real money. -- thorpej
