More than that: it's 80%-90% of the time *in which people DO think about
Singleton*, plus a few times in which that doesn't even come to mind.  Add
in a class instance masquerading as a module, as for example in
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/65207 , and
it must be over 90%.

But if you DO need to subclass the One And Only -- most of the remaining
8-9% of the time is covered by that -- then Borg is good.
