This generally means that the slave was in the process of
disconnecting when the reconfig occurred.  It's an unfortunate
consequence of the way we use PB for master/slave communication:
because it's an object-based RPC, the objects tend to stick around
after the connection itself is severed.

While we had a GSoC project to replace this protocol with a new one,
it wasn't quite ready for prime-time at the end of the summer.  Tom
had planned to finish it up and re-merge it, but I haven't seen any
work on that front in a long time.
