Have you read this thread on Software Transactional Memory?

It's about the downsides of STM.

Fantastic! :) I'd like something to temper my enthusiasm.

Well, I've had a browse, and it mostly seems to be a rant on the style
of, 'I don't like it, it sounds dangerous, ooooo, it's horrible, look at
it! These other people don't like it either!', without (that I've found
yet) a clear statement of why.

The main objection seems to be that software will end up being a mess of
shared state that many process are franstically writing too, but that
just seems like really bad design to me. Asynchronus message queues, it
suggests, are a better option.

I get the feel that there is a "holy war" between a functional approach,
and an imperitive approach here, somewhere. I'll need to read it more
closely, because that sounds interesting. I don't yet see why STM
shouldn't be highly functional though (I personally like functional a
lot).

Cheers,
