It only happens on that one machine.  My 32-bit laptop passes the test
in 15 seconds.  That 1.6 GHz Pentium 4 buildbot machine fails this test,
and takes 6 minutes to do so.

<niemeyer> I'm wondering why we have defineChecker() defined twice with exactly
           the same implementation under zope.security.checker...
<niemeyer> Is it some kind of high-availability system? :-)
