>Description:
An assertion is thrown when locking a normal mutex twice. Even if the
operation causes a deadlock, it should not assert.
>How-To-Repeat:
        #include <stdio.h>
        #include <pthread.h>

        int main()
        {
                pthread_mutex_t myMutex;

                pthread_mutexattr_t attr;
                pthread_mutexattr_init(&attr);
                pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_NORMAL);

                pthread_mutex_init(&myMutex, &attr);
                pthread_mutex_lock(&myMutex);
                pthread_mutex_lock(&myMutex);   // Assertion

                return 0;
        }
