locking foo ...

        I suspect that the appended is a better fix for
https://gerrit.libreoffice.org/#/c/3894/

        Though clearly the way this interacts with the boilerplate is not
terribly satisfying :-)

        Of course, ideally I'd like to undo -all- the locking, and assume that
in every case we require the solar mutex - except when the GUI thread is
idle - effectively serializing everything on the solar mutex: and then
ease that back in a few, selected cases where threading truly makes
sense but ... ;-)

        Thoughts ?
