The drain operation does not complete with a sync from the server but
with an event from the stream. Set a flag in the operation that it
completes with a sync. Keep all operations without a sync around in
the list.
Use a global sync that both syncs the globals and completes the
operations.
In the case of a card profile change, first the nodes are removed
and added and then the Profile and Route info updated. We need to
be able to bind to the new node and get the device.profile.id
before we can find the active port of the node.
See #279
Make sure we are watching the registry before we try to enumerate
objects.
When we wait for new object info, resync the pending operations
because they might depend on the info.
