You can do that, but then you're on your own for support.  Zope Corp
sometimes pays me to track down and fix Python bugs that affect Zope,
but they're not going to pay me to track them down a second time.

After you experience a segfault under heavy load, I doubt you'll be
posting a message here titled

    Help with sub-optimal memory behavior?

<wink>.

Most Zope users on WIndows don't even have C compilers, so Zope on
WIndows ships with precompiled binaries for everything Zope needs,
including Python.  So it goes.  You can build Zope from source on
Windows too if you want to, although it's an undertaking.  Note that
the Zope 2.7.2 info page:

    http://zope.org/Products/Zope/2.7.2/Zope-2_7_2-released

lists Python 2.3.3 as the minimum supported version.  That at least
means nobody at Zope Corp will pay attention if you try to report a
bug against Zope using an earlier version.  Zope 2.8 will require
2.3.4 minimum (because of the Zope-critical bugs still in 2.3.3 I
listed last time, which affect code Zope 2.8 inherits from the Zope 3
project).
