[issue35182] Popen.communicate() breaks when child closes its side of pipe but not exits

[Andriy Maletsky]

@josh.r but you’re correct regarding cached data that isn’t sent on subsequent communicate() calls. If the child consumes the input too slowly, and timeout occurs before sending all input, the remaining part will be lost.

Maybe it is not a bug, but it’s quite a confusing behavior, and I think it should be mentioned in the doc.
