I got loads of time for that, but I've also suffered at the hands of MSBuild as have thousands of others so the PR seemed like a funny troll at the time.
Seriously - I remember at one client there was a specific machine set up to edit the build on because it was the only one that could open the workflow editor without crashing. Why there was a workflow editor to edit MSBuild stuff I don't know but that's that world in a nutshell.
