The method I would use that is not RAM/CPU intensive would be to create a
memory-mapped file, take the size of the file, and increment your pointer to
file_length - tail_size.

The Windows API functions to look at are:
CreateFile
CreateFileMapping
MapViewOfFile

I'm sorry, but I'm not a ctypes guru so can't tell you how you would
accomplish this in python. (The C(++) code is fairly straightforward,
however).
