The only way writev can pick up an ENOBUFS error is in the call to
(*fp->f_ops->fo_write)(fp, &auio, fp->f_cred, 0) on line 447 (in -CURRENT).
ENOBUFS can happen on any network object if the system is completely out
of mbufs, right? So it could return ENOBUFS for any connected socket
specified as the fd in a write or writev operation.
