There's an OS X bug here. The problem is that pthread_mutex_trylock() does not
recognize PTHREAD_RECURSIVE_MUTEX_INITIALIZER. If you use that static
initializer and the first operation on the mutex is pthread_mutex_trylock()
then it will fail with EINVAL.
A recursive mutex using pthread_mutex_init() works. A recursive mutex for which
the first operation is pthread_mutex_lock() also works.
I filed rdar://10784745 in Apple's bug reporter.
