New submission from Geoff Alexander <gd...@us.ibm.com>:
I've found that subprocess.check_output() fails on Windows with OSError:
[WinError 87] when the current directory's name is too long:
```
Traceback (most recent call last):

```
Python's subprocess module should handle long directory and files names on
Windows where supported. For older versions of Windows that don't support long
directory and file names, an exception with a more informative error message
than "OSError: [WinError 87]" should be thrown.
