Argh, for some reason git send-email just won't work for me.  I it up,
it asks to confirm, I say, 'y', then nothing.  it just hangs.

Anyway, here's the patch as an attachment.  Will that work for you?

Subject: [prefix=PATCH] There seems to be a bug in the number of Parser
 threads created.  The number of threads is
 self.num_processes - 1 due to the range(1,
 self.num_processes).

This causes the Parser to hang at 0% on single core machines.

This fixes the Parsers to work on singlecore machines.

Applied. In the future, please stick to the conventions for git commit messages, and add a signed-off-by line. I've adjusted them when I applied it for now, you can look at that as an example of what to do. Thanks for the patch, it's much appreciated.
