Small nit after seeing a lot of these #if !ENABLE(OILPAN) in destructors. It
would be nice to have a small comment stating why the cleanup is not necessary
in oilpan. Otherwise it is up to the developer to figure out that e.g. weak
process is handling this in such and such object and off hand it can be a bit
magic if you are not aware of oilpan...

[Mads Ager (chromium), 2014/04/25 10:58:25]

Yeah, on the other hand there are complaints that the oilpan comments do not
make sense once we have oilpan. Adding a comment here stating that this is dealt
with using weak processing.

     SpeechInput* speech = speechInput();
     if (speech && m_listenerId)  { // Could be null when page is unloading.
         if (m_state != Idle)
             speech->cancelRecognition(m_listenerId);
         speech->unregisterListener(m_listenerId);
     }
