A longer-term goal of mine is to get rid of message_send_all(). That
call is the only reason why we still have serverid.tdb, which had been
a major performance bottleneck in the past. And without message_send_all
callers we can get rid of serverid.tdb completely.

The other option I thought of is to assemble the list of children in the
parent and forward that to the cleanupd. For that, it might be worthwhile
to change the children linked list into an array that we can send in
one chunk down.
