mmap copy-on-write under Win32

[Jay T Miller]

Hi,

My work group has started to work with python mmap as a possible
performance enhancer for programs which process large arrays under Win32
and several varieties of UNIX (Linux, Solaris, Tru64).  I'm trying to
use copy-on-write for mmaps on read only files and can't see how to do
this under the Win32 mmap.  Is this possible without modifying
mmapmodule.c?

Thanks,
Todd Miller
