I think this is probably the right approach. However, there's something
important to point out: flushing based on timing issues must be handled
*outside* of the conduit functionality, since by design conduit will not
allow you to (for example) run `await` for up to a certain amount of time.
You'll probably need to do this outside of your conduit chain, in the
initial Source. It might look something like this:
yourSource = do
mx <- timeout somePeriod myAction
yield $ maybe Flush Chunk mx
yourSource
