[issue21925] ResouceWarning sometimes doesn't display
New submission from Masami HIRATA:
It seems that ResouceWarning about unclosed file handles with '-W all' option
sometimes doesn't display.
Is this behaviour normal?

Masami HIRATA added the comment: It seems there is a misunderstanding on my part. Python v3.3.1 documentation says, "sys.flags The struct sequence flags exposes the status of command line flags. The attributes are read only." I think that sys.flags.hash_randomization should be always 1 on Python v3.3.1 because the documentation says, "-R Kept for compatibility.
