block stream/put?

[Keith Irwin]

Is there any scenario at all where

@(stream/put! stream data) ;; stream -> websocket-client

would block permanently?

[Zach Tellman]

In theory, yes. In practice, I'd expect that the TCP stack would
disconnect after a certain number of failures to send a packet, but I'm not
sure what the threshold for that is.

The result of, say, the other end of the connection failing to read but still hanging on to the connection?

Well, for that to happen you need to be ignoring the backpressure being
exerted by the core.async channel. If `put!` isn't telling you it's
succeeded, don't keep on putting.

and got the 1024 error (can’t `put!` more than 1024 items to a channel
before `put!` refuses).
