[New-bugs-announce] [issue23851] PEP 475: _posixsubprocess retries close() on EINTR

[STINNER Victor]

New submission from STINNER Victor:

According to the PEP 475, the close() function must *not* be retried if it fails with EINTR:

- http://alobbs.com/post/54503240599/close-and-eintr

The _posixsubprocess retries close() when it fails with EINTR. Example:

    while (close(fd_num) < 0 && errno == EINTR);

It should be fixed.
