14:24 <markos_> hello, I have a couple of questions and I would appreciate some pointers, I have multi-OS, multi-cpu, multi-compiler, multi-configuration CI that I want to build, I am using GitHubPullrequestPoller

14:25 <markos_> so I have created a dict of the configurations options and I create a BuilderConfig object for each unique instance

14:26 <markos_> that has the side effect that each config builder does a separate git checkout, can I do it in a way that is shared and I only change the following steps in the BuilderConfig?
