you serious? Making a Smalltalk image thread-safe is that hard?

What market are you talking about? There are lots and lots of customers of certain big database/appliance vendors that would loudly protest had the stuff they bought no inherent support for parallel execution.

And now it's arrived in tablets already. It's your problem if you leave your iPad lying around *outside* your house. ;-)

And do not forget the most important thing: people must be educated to program for parallelism. The computing power is there to be exploited, but programmers need to know how to exploit it. You can't rely on the compiler or VM alone.

Is it really *that* hard or is this just FUD?
