Duh, I figured out what's going on. I'm using a custom Formatter class, which
overrides format(). It's the job of format() to handle this, and ours doesn't!

Below is some pretty simple code and the resulting output.
Sometimes the code runs through but sometimes it just freezes for no
apparent reason.
The output pasted is where it just got frozen on me.
It called start() on the 2nd worker but the 2nd worker never seemed to
enter the run method.

They are telling you not to switch between editors that use tabs as tabs and
ones that use spaces as tabs. Python gets all wonky. No big, use one editor or
have your preferred editor highlight your non-preferred whitespace.
FWIW, I use spaces.

I have been looking at Erlang for that reason, but found it is missing useful

That line creates a class (i.e. "static") variable, which is unlikely
