Is it safe to get an answer via createAnswer(PRANSWER) and then
doSetLocal(ANSWER)
or createAnswer(ANSWER), setLocal(PRANSWER)? My intuition would have been
no [queue discussion of when callee.onaddstream() is called], but I'm willing
to be convinced it's safe. If so, though, we should probably explicitly state it
in the spec.
