Unregistration is a hack and we shoould either make the subsystems into

Fix operation status tracking.
...
An operation is rejected iff it has to be dropped before we can find an
upstream for it (unless we handle it ourselves, that is). At that point
it is failed unless completed successfully.
This makes a difference for multi-stage binds which alternate between
'failed' (we are waiting on a server response) and 'completed' (server
did what we asked them to, waiting on client to continue).

after a different bind had already been allocated to it, thus allowing
two binds to be in progress on the same connection.
