Hi all, I remembered a couple email threads discussing how it was possible to debug multiple DUnit processes from IntelliJ, but couldn't find a wiki article or a very complete description, so I wrote a wiki article. It's a little barebones right now, but there it is. Please edit or comment with any improvements you would like to make!
