Comments by Matt Ahrens from the issue tracker:
When a sync task is waiting for a txg to complete, we should hurry
it along by increasing the number of outstanding async writes
(i.e. make vdev_queue_max_async_writes() return a larger number).
Initially we might just have a tunable for "minimum async writes
while a synctask is waiting" and set it to 3.
