Allocate a cluster in such case. Actually, what is eventually supposed to happen (after I pop about five other projects off my stack) is that socket options are passed down in the kernel as uio structs, and don't get copied in until the appropriate lower layer has accepted them. (This also eliminates yet another use of mbufs to hold something other than packet data.) -GAWollman -- Garrett A.
