Summary: Enabling grinder.debug.singleprocess = true breaks my script

Initial Comment:
I have a script that currently works, and wanted to enable singleprocess because I'm getting _no_ errors when things run by workers fail for some reason. However, just enabling singleprocess makes the script exit early with the following error:

Why should setting single process change anything?
