[Peter Kasting, 2013/04/27 02:15:26]

I'm nervous about these two DCHECKs.  I think they can fail if something (e.g.
policy) clears your DSP in the midst of you interacting with instant.

I think instead of DCHECKing these you should do something like what my last
comment suggested, e.g. pass an empty keyword string to CreateSearchSuggestion()
and let it return you a no-destination match.  This will look weird but it's
better than crashing somewhere.

(Add a comment about why we have this weird edge case.)

[sreeram, 2013/04/27 02:21:56]

Done. I had added the DCHECK because Instant now listens for DSP changes and
resets state, so we ought not to hit the case you're worried about, but anyway.
