Cut down on the number of parentheses?

Done.

You call this ItemVerifier elsewhere. Can we stick to one name please -
preferably just "ItemVerifier".

Done.

AFAICT you don't test instantiating the queue using all available c-tors. The
test don't need to be exhaustive, but make sure each c-tor is used once.

[peah-webrtc, 2015/10/29 06:15:15]

Good point! And found an error that indeed did :-).

Done.

[kwiberg-webrtc, 2015/10/27 12:05:13]

Protect this with #ifdefs, since some of our platforms are pro-life and won't
allow death tests?

[peah-webrtc, 2015/10/29 06:15:15]

Done.

Initialize the vector empty, and use push_back to insert messages?
