The previous commits do not handle all of the edge cases of #583
appropriately. This is a short term solution that will work, but is not
as efficient as it could be. The whole refreshAccount function needs to
be reconsidered and replaced with a more sane way of handling atomic
updates to the user's account state.
Instead of emitting frames to each individual socket, group them into
socket.io rooms of people who can see hidden poll results and people who
can't, then just do 2 broadcasts.
If clients call it quickly in succession with large playlists, it can
cause node to get stuck stringifying socket.io frames and cause an out
of memory crash.
