It's not true on macOS either. Threads can have different working directories for instance.

I'd be interested to know how to do that. Go's Chdir() calls SYS_CHDIR on Darwin, and Posix requires that chdir affects the whole process.

In Linux you can unset CLONE_FS when creating a thread, but the Go runtime does not do this.

I note the Windows docs[1] say "Multithreaded applications and shared library code should not use the SetCurrentDirectory function" (which Go's Chdir() calls)

SYS___pthread_chdir exists on mac os.
