Just out of curiosity: why do you prefer singletons to Borgs in
the first place?

(I don't see Borg as a hack to get the behaviour of a singleton; I
see it as a more direct way to solve the problem which singletons
are supposed to solve.  Thus to me Borg is actually preferable, in
those exceedingly rare cases when that problem actually arises.)
