[Python-Dev] How to customize CPython to a minimal set

Hi, all There is a request to run python in a Linux-based embedded resource constrained system with sqlite3 support. So many features are not required, like posixmodule, signalmodule, hashtable ... But seems there are some dependencies among the Modules/Parser/Python/Objects/Programs... Is there a way to tailor CPython 3 to a minimal set with sqlite3 (the less syscalls the better) ? Is it possible to do that? Thank you.
