This probably doesn't hurt but we actually don't want to unlock this - the context is only locked once when its no longer accepting writes.
I wonder if its possible that this goroutine can gets pre-empted and another tick can fire before we swap in a new context? In that case we'd block the timer thread completely waiting on the lock... Best to leave the unlock here for now in that case!

I think you are right!
