[issue8586] test_imp.py test failures on Py3K Mac OS X

I'm seeing a "similar" (but not identical) failure on py3k / Windows 7 in test_marshal. Failure in the same code path in support.py:

======================================================================
ERROR: test_floats (__main__.FloatTestCase)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "../Lib/test/test_marshal.py", line 14, in helper
    f = open(support.TESTFN, "wb")
IOError: [Errno 13] Permission denied: '@test_5324_tmp'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "../Lib/test/test_marshal.py", line 88, in test_floats
    self.helper(f)
  File "../Lib/test/test_marshal.py", line 26, in helper
    support.unlink(support.TESTFN)
  File "C:\compile\py3k\lib\test\support.py", line 186, in unlink
    os.unlink(filename)
WindowsError: [Error 5] Access is denied: '@test_5324_tmp'
