Ok, yes.

Sorry for being stupid.. but:

- so when I suspend a response without invoking a new thread nothing happens except that a connection is being used
  (meaning that a queue of 1000 responses would use up 1000 connections)

- when I resume the response, the response will be sent in the current thread of execution.

That's simple, but I find the implications not so easy to see at first. Thanks.

What I would love to be able to do is to suspend/resume again. Considering server push, it seems odd that I can have a long running request without resource consumption *until* the first bits of the response are sent. What if I want to send one event every Minute? The initial async doesn't really buy me that much, does it?

(just trying to get my head straight)
