FWIW, BSD folks unlock the socket for the duration of mknod - mark it as "somebody's trying to bind it" to avoid the fun with racing double bind(), but that's about it. Tempting, to be honest...
BTW, why does unix_autobind() do allocation under ->readlock? The allocation will be normally used - that if (u->addr) return; part is just dealing with an unlikely race, as far as I can see...
