[issue24864] errors writing to stdout are uncatchable and exit with status 0

[Robert Collins]

Robert Collins added the comment:

Oh, one nuance - the reason my except isn't triggering is that the write is happening in interpreter shutdown - in flush_std_files.

Adding a a flush there allows that to work, but its fugly:

---
import sys

try:
    print("What... is your quest?")
    # Workaround bug 24864: force the write to be immediate
    sys.stdout.flush()
except:
    sys.stderr.write("Exception in program.\n")
    e = sys.exc_info()[1]
    try:
        # Workaround bug 24864 close the file so flush_std_files doesn't run
        # during interpreter cleanup.
        sys.stdout.close()
    finally:
        raise e from None
