Polls are transient and lose their state on connection loss

Ideally they would persist across reconnects.

Should they also retain state across program exit/restart? What about the duration?

Duration is left untouched, so in the case where the poll duration expired when the program was not connected, it will immediately end upon rejoining the relevant channel.
