Because it is more obvious that _isowned() is for the current thread
than _islocked().  As you can tell by my previous (incorrect) 
assumption.

There is prior art for this outside of FreeBSD.  Solaris has
mutex_owned() as part of their kernel mutex API.  I would
suggest using pthread_mutex_owned_np().  Hmm, even FreeBSD has
mtx_owned() :-)
