This had me confused, especially the source->source part.  Perhaps
call the parameter "loose" so loose->source is the way for somebody
who has a odb_loose_source to learn what odb_source it belongs to,
or something.  Of course the round-about way to clera the cache that
now belongs to odb_loose_source by taking odb_source looked awkward
in this step, but that awkwardness goes away immediately in the next
step.  And the parameter of type "odb_loose_source *" called "source"
here, instead of "loose", still hurts after the next step [07/13] is
applied.
