progress: retry ferr.flush() and .write() on EINTR (issue5532)
See the inline comment how this could mitigate the issue.
I couldn't reproduce the exact problem on my Linux machine, but there are
at least two people who got EINTR in progress.py, and it seems file_write()
of Python 2 is fundamentally broken [1]. Let's make something in on 4.2.
