It does as there exists various thread implementations. For "tasks",

All threads (within the same process) share the same memory and file

What is a "thread group"?
fork(2) creates a new process - read: it creates new memory maps which
are copy-on-write-references to the ones of the parent are - and it
starts the first "thread" in that process.
CreateProcess() does basically the same (IMMSC - it's > 10 years that I
