okay, that was easy enough, whats next?
say, after you call paused(), write should return false
until resume is called.
simple way to implement this:
write must return !paused
after pause() paused = true
after resume() paused = false
on resume, if !paused drain is emitted again.
after drain, !paused
there are lots of subtle ordering bugs in streams.
example, set !paused before emitting drain.
the stream api is stateful.
