[New-bugs-announce] [issue12493] subprocess: Popen.communicate() doesn't handle EINTR in some cases

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

subprocess.Popen.communicate() doesn't catch EINTR error if it is called without timeout and if there is only one PIPE (stdout or stderr).

Attached patch fixes these cases. It may need a test.

I found this bug while working on test_signal, especially on the inter process signal tests.
