I agree with this. I was talking to a someone recently who works on embedded system. They do quite a bit of threaded code to deal with network, UI, and other aspects. I mentioned I prefer message passing and processes to threads. His response was that in the limited resources of their devices, that was not feasible. Shared memory and a single process saved on very valuable limited memory. I mainly work on server side code where for the most part, the overhead of a separate process is not issue. The overhead of not sharing memory is not an issue.
