If that's your audience, then you should give them a library/framework/language that hides all the complexity. I'm currently spending a lot of time working on Python Tornado stuff on an embedded device, and I can say that the lack of threads does not substantially reduce the number of ways you can screw things up.

They aren't my audience... they're my coworkers. Sometimes I get to pick how we do a project and sometimes I'm there to help them with their project. If they chose to use threads, I generally try to escape quickly.

No experience or comment on Python/Tornado. We don't really do a lot of web stuff.

But sure, people can screw things up in lots of ways. However, once a threaded program is screwed up, you really only fix it by starting a new version - it's near impossible to incrementally fix race conditions and dead locks - you can't reliably repeat the bug to debug it. Bugs in non-threaded code can at least be tracked down one by one.
