@jaswdr Hm, this is was somewhat unexpected for me, since when reading directly from pipe, and EOF is sent.

Timeout was somewhat awkward in my case, since I don't know when other process will start sending, and how long it would take. On the other hand, I use asyncio loop, and can do this asynchronously, so I get notified when child process dies, by other means, and close the stream. So there are plenty of possible workarounds, but I'm not sure it is impossible to solve the problem on the library level yet. It would take more digging into implementation from my side, however.
