So sorry that i'm stressing this, hopefully it's the final message.
Apples iterative kernel-update strategy resulted in these versions:

    14:02 ~/tmp $ /usr/sbin/sysctl kern.version
    kern.version: Darwin Kernel Version 10.8.0: Tue Jun  7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386
    14:02 ~/tmp $ gcc -o zt osxversion.c -framework CoreServices
    14:03 ~/tmp $ ./zt 
    OS X version: 10.6.8
    apple_osx_needs_fullsync: -1

I.e. the new patch uses >10.7.0 or >=10.6.8 to avoid that
FULLFSYNC disaster (even slower than the Macrohard memory
allocator during "Wintel" partnership!), and we end up as:

    14:03 ~/src/cpython $ ./python.exe -E -Wd -m test -r -w -uall test_mmap
    Using random seed 8466468
    [1/1] test_mmap
    1 test OK.

P.S.: i still have no idea how to do '-framework CoreServices'
regulary.  Like i've said in #11046 i never used GNU Autoconf/M4,
sorry.  You know.  Maybe the version check should be moved
somewhere else and simply be exported, even replacing the stuff
from platform.py?  I don't know.  Bye.
