 The reason seems to be (http://elliotth.blogspot.dk/2012/04/gettid-on-mac-
 os.html):

   Speaking of 10.6, there's also a non-portable pthread_threadid_np(3)
 that turns a pthread_t into a uint64_t. This gives the same values you'd
 get from thread_selfid(2). Again, this is unsupported in 10.5 and earlier.

 Best regards
