In Win32, DLL's are "pre-linked" using a specified base address.
When the DLL is loaded, an attempt is made to place it at
that address.  If that address is already in use, a new base address
is selected, and the DLL subject to fixups.  Apparently, these
fixups are very slow, and significant performance gains can be
made by selecting a good base address.

This document is to allocate base addresses to core Python 
and Python .PYD files, to give a better change of optimal performance.
This base address is passed to the linker using the /BASE
command line switch.
