The Windows implementation of listdir returns
successfully as soon as FindNextFile returns False,
without checking that GetLastError returns
ERROR_NO_MORE_FILES. If the operation is interrupted
(eg removable media ejected, network connection to UNC
path lost, and so on) an incomplete directory listing
is returned instead of throwing an exception.
This behaviour exists in 2.4.3 and 2.5b2.
