Maybe we should rename this method to reflect the fact that it is used after
options are changed.

[Brian Wilkerson, 2015/10/28 02:09:08]

Is that the only time it's used? (I actually prefer names that indicate what the
method does, rather than when it's used.)

Maybe `invalidateResults` or something?  It's pretty nuclear.  Or maybe
`nuclearOption`? ;)
