Great thanks Armin!
I found out we did call python code from different theads.
Here are my understanding, please correct me if I am wrong:

In main thread:
rpython_startup_code();
pypy_init_threads();
res = pypy_setup_home(..);

And in other worker thread, after main thread do the initilization:
pypy_thread_attach();

Will there any problems if main thread exit before other worker thread do
the initilization "pypy_thread_attach()"?
