Summary: os.path.exists returns false negatives in MAC environments.

Initial Comment:
In Mandatory Access Control environments (such as
SELinux), it's quite possible for stat to fail with
permission denied. In this case, os.path.exists will
return False incorrectly. The simple(ish) fix is to
check for an access denied error (which would indicate
present, but not readable) when using stat to check for
existence of files.
