// 2 threads may _ever_ call _any_ Python code (including INCREF/DECREF) without
// first having this thread lock.
//
// The second type of lock is a "global framework lock". This lock is simply a
// critical section, and used whenever 2 threads of C code need access to global
// data. This is different than the Python lock - this lock is used when no Python
// code can ever be called by the threads, but the C code still needs thread-safety.
// We also supply helper classes which make the usage of these locks a one-liner.
