No, to be honest I really don't want to be using any approach that
requires checking of threads. There is definitely an incorrect meshing
of design and use cases if this is required. Keep in mind that I don't
want to do anything fancy with the TrackPtrs, aside from enter them in
the database (they should *not* be renamed, moved, organised or
modified in anyway).

Perhaps it would be better to augment CollectionLocation with a method
that would allow a direct insertion of tracks into the database,
similar to what insertTracks( const QMap<Meta::TrackPtr, QString>
&trackMap ); does in SqlCollectionLocation.
