Comment (by itamarst):

 From the above we can extract two problems:

 1. A need for backpressure.
 2. `_write()` waiting for Deferred to fire before continuing. If the need
 for backpressure didn't exist, this would be bad. Given backpressure is
 necessary... this might be OK. Or not, perhaps there is a better
 mechanism.

 So step 1 is probably figure out how to implement backpressure.
