[issue24699] TemporaryDirectory is cleaned up twice

[Ilya Kulakov]

New submission from Ilya Kulakov:

I'm seeing the issue using python 3.4.3 on Windows 8

In the __init__.py method of my package I define temporary directory at the module level like this:

_TempDir = tempfile.TemporaryDirectory(prefix='...'))
tempfile.tempdir = _TempDir.name


I expect it to be deleted on exit.

However, _sometimes_, I'm seeing the following exception on exit:

Traceback (most recent call last):
  File ":/weakref.pyo", line 582, in _exitfunc
  File ":/weakref.pyo", line 506, in __call__
  File ":/tempfile.pyo", line 674, in _cleanup
  File ":/shutil.pyo", line 478, in rmtree
  File ":/shutil.pyo", line 360, in _rmtree_unsafe
  File ":/shutil.pyo", line 358, in _rmtree_unsafe
FileNotFoundError: [WinError 3] The system cannot find the path specified: 'C:\\
Users\\BC79~1\\AppData\\Local\\Temp\\..._s9wqmyo_'
