Remove PyThread_type_lock (now uses PyMutex internally). Add new benchmark options: - work_inside/work_outside: control work inside and outside the critical section to vary contention levels - num_locks: use multiple independent locks with threads assigned round-robin - total_iters: fixed iteration count per thread instead of time-based, useful for measuring fairness - num_acquisitions: lock acquisitions per loop iteration - random_locks: acquire random lock each iteration Also return elapsed time from benchmark_locks() and switch lockbench.py to use argparse.
Tests in this directory are compiled into the _testinternalcapi extension. The main file for the extension is Modules/_testinternalcapimodule.c, which calls `_PyTestInternalCapi_Init_*` from these functions. See Modules/_testcapi/README.txt for guideline when writing C test code.
