Because we didn't send anything, its waiting for input from remote-curl, and remote-curl cannot read its response payload because doing so would lead to a deadlock. Send the background task EOF on its input before we try to read its response back, that way it will break out of its read loop and terminate. Signed-off-by: Shawn O.
