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: http://cert.uni- stuttgart.de/archive/bugtraq/2001/07/.html
