Comment(by nickm_mobile):

 I'm not sure I'm comfortable with that.  Honestly, you may have to talk me
 out of doing this in 0.2.2.

 That said, there is a much simpler fix, if we can trust the compiler not
 to get too smart.  Instead of setting i_has_been_chosen to 1 (as we do in
 the current code), set rand_bw t the o INT64_MAX (or whatever its type's
 max is).  Remove i_has_been_chosen. Should work I think.
