 I see an option. The start could set the token to something specific at
 its
 start. Then when the getToken looks for the token, it could detect it was
 not
 set to something else.

 Or, I can do all this in the #2375 inside getNextToken(). That sounds
 cleaner,
 so I think this branch can be merged.
