To access thread-specific data using pthreads, you first need to take a lock and call pthread_key_create(). Since the whole point of thread-specific data is to avoid taking a lock, the API is useless.

You’ll need an alternative to the cross-platform pthread API for accessing thread-specific data. Otherwise, the cost of that API will dominate any other cost, and it won’t be worth our time to try to optimize other things.
