Comment 6 for bug 113085

I have created a branch that does not catch the SystemError any longer. This resulted in some errors during an update that I also fixed. I'd be really happy if somebody could review it so that it gets released soon. It will make a lot of failing buildouts happy, because they'll fail at the right step.
The branch is here:
svn+ssh://svn.zope.org/repos/main/zc.buildout/branches/do3cc_exitcode
