Summary: Hang using files named prn.txt, etc

Initial Comment:
Windows reserves many possible filenames as reserved 
device names.

Examples are prn.xxx, con.xxx, com1.xxx aux.xxx, etc, 
where xxx can be any extension.  Attempts to 
create/read/write to these files can hang the 
interpreter, but ideally would just throw an OSError.

A partial list of device names is mentioned at:

Did you read the message you referenced with that URL?  I 
agree with it:

"""
Conclusion : applications should not filter out DDNs, 
because they don't fix the problem (basically they make it 
even worse), the OS patch is better because it
fixes *ALL* problems, ...

CONCLUSION : patch your OS, and stop whining about so
called 'bugs' in applications, you will never be able
to completely patch the problem that way.
"""

They're right:  applications cannot fix this; if it's a 
problem for you, then you should download and apply the MS 
OS patches linked to from that article.
