David got an oops the other day while posting the admin form for a 
language (taken from OOPS-1550O2497):

  ShortListTooBigError: Hard limit of 1000 exceeded.

    Traceback (most recent call last):

ShortListTooBigError: Hard limit of 1000 exceeded.

This happened with Spanish, which is obviously a pretty "big" language. 
 But I doubt the number of countries it's spoken in will have broken 
through the limit of 1,000.

ISTRM the API breaking sometimes when lists got too long...  could it be 
the number of people interested in a language that exceeds this limit? 
If so, why is it being queried in the first place?
