Current status:
I'm leaving the PR without additional indentation for the Vthread stack on
purpose because I plan to add a new PR to include @tstuefe's changes (unless
those changes get merged very quickly)
@AlanBateman I've included the vthread's name in the output as per your
suggestion.
This what the output looks like at the moment:
