Jay,

My initial concern was that a slave device could disappear out from
under us, but it seems like this certainly isn't the case since all
calls to bond_release are protected by rtnl-locks, so I think you are
correct that we are safe.  I'll test this on my setup here and let you
know if I see any problems.
