What other times is validation ignored?

See Ticket #185:
  http://dev.rubyonrails.org/trac.cgi/ticket/185

I think << should only associate records, not silently create new ones
or save/validate content fields.

has_many << updates the associate record's foreign key and
has_and_belongs_to_many << inserts a row in the join table.  Neither
touches the associate record's content; hence, neither requires full
save/validation.
