"ctdb reloadips" use of ipreallocate() can result in a spurious
takeover runs. This can cause a subsequent "ctdb reloadips" to fail
to disable takeover runs (due to there being one already in progress).
There are various possible improvements but a proper fix probably
requires a protocol change. That would mean receiving an ACK for a
takeover run request to indicate that the request will be processes
and then a broadcast to indicate a completed takeover run.
There are various other partial fixes (e.g. de-duping queued takeover
run requests against those in the in-progess queue) and workarounds
(e.g. always do a double ipreallocate() in the tool, which should
absorb the spurious takeover run).
However, this is unlikely to be a real-world problem. Real use cases
should not involve repeatedly reloading the IP configuration.
Instead, work around the problem of flaky tests by manually adding
"ctdb sync" commands to cause extra no-op takeover runs. These should
not add spurious takeover runs and will create synchronisation points
to help avoid the issue.

Move the opening brace for the action to make the implicit

An alternative would be to revert the removal of the explicit

that an author of future code will necessarily use explicit

the join handler is unregistered. However, if another MSG_ID_JOIN is
received before the join handler is unregistered then MSG_ID_SYNC is
re-broadcast. This results in multiple attempts to unregister the
join handler.
Once all MSG_ID_JOIN messages are received, unregister the join handler
to ignore any extra MSG_ID_JOIN messages. Also, make sure that while
join handler is being unregistered, MSG_ID_JOIN messages are ignored.
