Default Forking and overhead in FreeBSD

I thought I read somewhere that FreeBSD implemented some method where forking was now virtually the same overhead as setting up threads. There's some guy arguing with me that everything in the 'nixes is done with forking, not threading, and windows is so much better, blah blah blah, which is what made me think I had read something somewhere about that.

There is a FreeBSD Threads mailing list.


What exactly is windows better at managing threads? And is he programming in .NET?

He is probably biased towards threads due to the fact that forking a process in Windows is expensive. Here is part of a discussion on threads and forks on the python mailing list that is quite applicable:
I think you're overestimating the sophistication of the average
extension developer, and the hardware to which they have access.

Nevertheless, you're right the GIL is not as bad as you would
initially think: you just have to undo the brainwashing you got from
Windows and Java proponents who seem to consider threads as the only
way to approach concurrent activities.

Just because Java was once aimed at a set-top box OS that didn't
support multiple address spaces, and just because process creation in
Windows used to be slow as a dog, doesn't mean that multiple processes
(with judicious use of IPC) aren't a much better approach to writing
apps for multi-CPU boxes than threads.

Just Say No to the combined evils of locking, deadlocks, lock
granularity, livelocks, nondeterminism and race conditions.
