Image.open with non-image file raises IOError without closing the file

[ZMI-JacobGeiman]

Attempting to open a non-image file and catching the IOError causes the file handle to be left open, meaning this file cannot be modified by the process/os until the application stops.

Example code:

from PIL import Image
import os
path = '/path/to/non/image'
try:
    Image.open(path)
except IOError as err:
    print 'This is not an image file'
os.remove(path)

I am running Pillow 3.1.1 on Python 2.7.6
This should be fixable by calling fp.close() before raising the IOError in Image.open

Just to confirm, you're running Windows, yes? I ask this because #1651 indicates that this is a Windows issue.

You may also be interested in #1144

[ZMI-JacobGeiman]

yes, this was on Windows 7.

Okay then. Do you mind if this issue is closed as a duplicate then? Between #1651 and #1144, I believe that this is covered.

please close. Thanks
