I don't think so. fork() gives you two copies of the C stack,
and copies of global variables (including those used by the
standard library, e.g. environ, stdout, etc.), and two copies
of OS-related data structures (pids, signal handler tables, etc.).
Offhand I don't know exactly what _beginthread() does,
and I don't have the appropriate documentation on hand,
but generally threads share the same global variables,
and the child thread gets an empty stack, not a copy of
the parent's stack.
