I have merged these two branches to their respective trunks:

z.i: https://mail.zope.org/pipermail/checkins/2011-September/057121.html

z.c: https://mail.zope.org/pipermail/checkins/2011-September/057124.html

If no one has issues with this, I will make releases of both within the
next few days.

- C
