pthread_mutex_lock() now uses a better algorithm which goes much faster in multithreaded environments that have lock contention. This comes at the cost of adding some fixed-cost overhead to mutex invocations. That doesn't matter for Cosmopolitan because our core libraries all encode locking operations as NOP instructions when in single-threaded mode. Overhead only applies starting the moment you first call clone(). |
