[issue1191964] asynchronous Subprocess

[akira]

akira added the comment:

Could `read_nonblocking()`, `write_nonblocking()` raise OSError(EAGAIN) (it could be named `ResourceTemporarilyUnavailableError`) if read/write would block?

It would allow to distinguish EOF (permanent condition) from "read/write would block" (temporarily condition) without additional API calls.
