Summary: size limit exceeded for read() from network drive

Initial Comment:
If you've got a network share mounted as a local drive
then Windows has a limit of 67,076,095 (0x03ff7fff)
bytes for a read from an open file on that drive.

Running the python read() method on an open file larger
than this size throws an "IOError: [Errno 22] Invalid
argument" exception.

A fix would be for python to internally use multiple
reads so as to not exceed this limit.
