Dropped features

The features below are dropped because they are not useful in "tiny" multi-threading environment. As a general rule, they have never been supported in the future.

• pthread_atfork()
• pthread_cancel()
• pthread_key*()
• pthread_getspecific()
• pthread_setspecific()
• sem_open()
• sem_unlink()
