I doubt that works. As python uses the OS underlying threading model, it doesnn't know about the internal management structures - and even it knew, these had to be carefully designed for that exact purposes of yours, as the stack frame can only be safely inspected by the thread _running_ in it. An external thread could be interrupted at all times while traversing other threads management structures, and then find a corrupted memory location when it is re-scheduled. Maybe one could write a threading model that allwos for hooks in the scheduler (which has all the time in the world for such stuff) - but I'm not aware that that's possible under e.g. pthreads, so there is unlikely a python-way to do so.
