which unfortunately doesn't help anyone who has a dreamplug which
comes shipped as standard with a 2.6.32 <= .35 kernel. especially on
learning that the default shipped kernel just works and on learning of
this dog's dinner mess don't want to go anywhere near a kernel
upgrade.

it would seem that udev would have to dynamically work out "do i have
the accept4 function call, if so use it, if not then do what was being
done previously".
or... just don't use accept4 at all.

i can't pretend to know what accept4 does, so can't say.

it's not. the exact reason's not clear yet.
