I guess we could simply not recurse if the recursion depth is too big? At some point we have to let the recursive calls finish in order to let the local variables and stack frames be garbage collected. -- Martin Geisler VIFF (Virtual Ideal Functionality Framework) brings easy and efficient SMPC (Secure Multiparty Computation) to Python.
