Clemens Backes 3a44f269c5 [base] Avoid pthread_rwlock_t on Mac ... pthread_rwlock_t can deadlock on Mac if signals are sent to the process in the wrong moment. Since we use processes e.g. for sampling profiling (in both d8 and in Chrome), we hence cannot safely use pthread_rwlock_t on Mac. Instead, fall back to a non-shared pthread_mutex_t. Interestingly, this shows no measurable performance impact in Wasm compilation on my MBP.
