Why do you think that UNIX systems are better at handling large shared
buffers than Wndows?
32 bit Windows systems can suffer from fragmented address space, to be
sure, but if the
performance of the operating-system supplied mutex or semaphore isn't
good enough, you can
just use the raw atomic ops.
If what you mean is that pg has a design that's heavily oriented towards
things that tend to
be cheap on POSIX and doesn't use the core Win32 features effectively,
then let's track
that as an optimisation opportunity for the Win32 port.
