Right, the async=false alone won't help since the queue will still fill
up and prevent the other sink from prerolling.

As for increasing max-size-time, you would need to unset/increase all
max-size-* since the limit hit first wins.

Unfortunately not (to my knowledge).

If a pipeline fails to preroll, the general rule is to look at where
data flows and where not, that is: why does data not make it all the way
through to all sinks.
