CPython >=3.2 detects files (and sockets) not closed explicitly or via
__exit__() and can print ResourceWarnings.
$ python2.7 -Wd -c 'open("/dev/null")'
$ python3.1 -Wd -c 'open("/dev/null")'
$ python3.2 -Wd -c 'open("/dev/null")'
-c:1: ResourceWarning: unclosed file <_io.TextIOWrapper name='/dev/null'
