There's no reason to believe that reconnecting to ovsdb-server will
resolve an unhandled exception in python-ovs. In addition, since users
often subclass Idl and add their own notify() methods, there could be
exceptions thrown from that code.
The best we can do is log what is going on and rely on users to fix
the issue. Delaying with sleep() is usually a bad idea since if there
was some kind of ovsdb reconnection, it will delay calls to Idl.run()
which will handle that reconnection over several calls.
