WindowsError: [Error 5] Access is denied

I get this error from **ffedc.py**:

```
File "C:\Python27\lib\site-packages\audioread\ffdec.py", line 279, in __exit__
self.close()
File "C:\Python27\lib\site-packages\audioread\ffdec.py", line 263, in close
self.proc.kill()
File "C:\Python27\lib\subprocess.py", line 1002, in terminate
_subprocess.TerminateProcess(self._handle, 1)
WindowsError: [Error 5] Access is denied
```

I've been searching how to resolve it and found this on stackoverflow:
https://stackoverflow.com/questions/17076679/windowserror-access-is-denied-on-calling-process-terminate

But even trying this try-catch trick doesn't work when I modify **ffdec.py**.
Looks like issue might be related to this:
https://stackoverflow.com/questions/5573257/windowserror-error-5-access-is-denied-when-trying-to-kill-a-subprocess-pytho

But still don't know how to resolve. I tried running my code with admin privileges too and I have all the permissions to modify my file.

Start by reproducing the Windows failure in ffdec.py, focusing on __exit__ and close where self.proc.kill() calls subprocess termination. Compare the reported behavior with the linked Windows subprocess discussions and verify the result on Windows. Done means the decoder closes without raising Access denied.
