 The gcd.c implementation has this cryptic comment:

 // TODO: These structures need to be wrapped in a Data struct,
 // otherwise there are crashes when one tries to add an instance
 // variable to a queue. (Not that that is a good idea.)

 At first I ignored this, but later it occurred to me that this may be why
 I am unable to subclass Dispatch::Group (to use for a Future, which
 contains an instance variable).  Is that correct?  If so, is there a
 particular reason why subclassing these would be  bad idea?
