https://play.golang.org/p/jIKQ1npwUl

1. What did you expect to see?

It should not deadlock.

1. What did you see instead?

It deadlocks trying to read bytes from a network connection that are never delivered.

Note that the code in question was trying to get around issue #12796,
which means that the net/http code can still read from a request body
after the roundtripper has returned.

Ah, my fault - the client response body wasn't closed,
which means that the request will never be considered complete.

Closing this issue.
