alex 1998/08/02 10:04:25 PDT Modified files: lib/libc_r/uthread uthread_mutex.c Log: Fixed a race condition during the first lock/trylock of a statically initialized mutex. Statically initialized mutexes are actually initialized at first use (pthread_mutex_lock/pthread_mutex_trylock). To prevent concurrent initialization by multiple threads, all static initializations are now serialized by a spinlock.
