iotest 169 uses the 'new' module to add methods to a class. This module
no longer exists in Python 3. Instead, we can use a lambda. Best of

Python 3.2 introduced the inheritable attribute for FDs. At the same
time, it changed the default so that all FDs are not inheritable by
default, that only inheritable FDs are inherited to subprocesses, and
only if close_fds is explicitly set to False.
Adhere to this by setting close_fds to False
There are two imports that need to be modified when running the iotests
under Python 3: One is StringIO, which no longer exists; instead, the
StringIO class comes from the io module, so import it from there. The
other is the ConfigParser, which has just been renamed to configparser.

some places, it adds version-specific code and decides what to do based

In Python 3, several functions now return iterators instead of lists.
This includes range(), items(), map(), and filter(). This means that if
we really want a list, we have to wrap those instances with list(). On
