# This exception was "raised" in the TemporaryDirectory.__del__ method,
# if the "osc2.util.io" was already "unloaded" (the __del__ method
# calls the _cleanup method, which tried to call the
# os.path.isdir function).

# If the "osc2.util.io" module is passed to _PyModule_Clear
# (Objects/moduleobject.c), almost all entries in the module dict are
# set to None. That is, the entry for the key "os" points to None.
# Now, suppose that there is still a TemporaryDirectory instance
# around, whose __del__ method is eventually called. During this call,
# "os" resolves to None and therefore the subsequent lookup for the
# name "path" leads to the AttributeError.
# Instead of raising this exception, it is just printed to stderr,
# because it occurred in a __del__ method (see slot_tp_del
# (Objects/typeobject.c) and PyErr_WriteUnraisable (Python/errors.c)).
