No. Your approach won't work very well, either, since threads can come
out nowhere: A C module may create threads, and just temporarily enter
Python from the thread.

If you want to hook into all threads, you need to hook into
PyThreadState_New and friends.

If you want a future-proof way, I recommend to create a
per-interpreter state global, and hook into all places that use the
trace function. You might want to try writing a PEP to generalize this
feature.

Martin
