cpython threads map to os level threads. however due to the gil, only one thread per process may be executing python code. python c extensions may release the gil before invoking apis, a database adapter will for example release the lock before executing a query, to allow other threads a chance to execute. the internal management of the gil allows fine tuning of how often the threads are switched via sys.checkinterval api.
