This test doesn't pass on Windows. The cause seems to be that chmod
doesn't support the same funcationality as on Unix. I'm not sure if
this fix is the best (or if it will even work)--it's a test to see
if the buildbots start passing again.
It might be better to not even run this test if it's windows (or non-posix).

SF patch #1630975: Fix crash when replacing sys.stdout in sitecustomize
When running the interpreter in an environment that would cause it to set
stdout/stderr/stdin's encoding, having a sitecustomize that would replace
them with something other than PyFile objects would crash the interpreter.
Fix it by simply ignoring the encoding-setting for non-files.
This could do with a test, but I can think of no maintainable and portable
way to test this bug, short of adding a sitecustomize.py to the buildsystem
and have it always run with it (hmmm....)
