 I encountered the following failure in the testsuite driver while bringing
 up the new Windows build bot,

 From the repl it indeed seems that `ctypes.cdll.kernel32` is broken,
 {{{
 $ python
 >>> import ctypes

   File "<stdin>", line 1, in <module>

 Tamar, do you have any idea what is going on here?
