> Windows doesn't have fork()

It does (or maybe did, not sure if it still works) have the literal equivalent of fork() - NtCreateProcess() with NULL SectionHandle argument creates a new process which is a clone of the caller. However, it never really worked. The Win32 API did not support forking, and so any process which forked itself and then tried to invoke any Win32 API calls would soon crash or fail mysteriously. In theory forking did work for pure NT API applications, but those are rather limited in their abilities.
