Can a multi-threaded program ever be deterministic?

Question

Normally it is said that multi threaded programs are non-deterministic, meaning that if it crashes it will be next to impossible to recreate the error that caused the condit

Answer 1

Normally it is said that multi threaded programs are non-deterministic, meaning that if it crashes it will be next to impossible to recreate the error that caused the condition.

I disagree with this entirely, sure multi-threaded programs are non-deterministic, but then so are single-threaded ones, considering user input, message pumps, mouse/keyboard handling, and many other factors. A multi-threaded program usually makes it more difficult to reproduce the error, but definitely not impossible. For whatever reasons, program execution is not completely random, there is some sort of repeatability (but not predictability), I can usually reproduce multi-threaded bugs rather quickly in my apps, but then I have lots of verbose logging in my apps, for the end users' actions.

As an aside, if you are getting crashes, can't you also get crash logs, with call stack info? That will greatly aid in the debugging process.
