Yes, with select-active-regions enabled, it is a serious problem if
C-SPC and making an active region messes with the primary.  So, for the
moment, I went ahead and changed x-select-enable-primary to nil, as you

But I think select-active-regions needs further improvement.  Perhaps
its default behavior should be as follows: for an active region created
using shift-selection or mouse dragging, Emacs supplies the region text
to primary.  When such a region is deactivated, Emacs disowns primary
(as some other apps do, tho not Firefox).  For an active region created
simply with C-SPC, no special x-selection handling should be performed.

We could give select-active-regions a new default value, `shift-select',
which would have the above meaning.
