There is a simple universal IO loop, taking care of events, timers and sockets. Primarily, one instance of a protocol should use exactly one IO loop to do all its work, as is now done in BFD. Contrary to previous versions, the loop is now launched and cleaned by the nest/proto.c code, allowing for a protocol to just request its own loop by setting the loop's lock order in config higher than the_bird. It is not supported nor checked if any protocol changed the requested lock order in reconfigure. No protocol should do it at all.
