Please file a bug.  We are ignoring it if it's zero.  We should be
ignoring it if it's negative.  I'm not sure how complex this will be
internally to fix. 

However, as others have pointed out, this shouldn't stop you restricting
the number of accepted connections to 1.  You just won't be able to
restrict it to zero.
