pthread_kill_other_threads_np() has an effect only in the LinuxThreads threading implementation.  On that
       implementation, calling this function causes the immediate termination of all threads in the application,
       except  the  calling  thread.  The cancelation state and cancelation type of the to-be-terminated threads
       are ignored, and the cleanup handlers are not called in those threads.

       pthread_kill_other_threads_np - terminate all other threads in process

pthread_kill_other_threads_np() is intended to be called just  before  a  thread  calls  execve(2)  or  a
       similar  function.   This  function  is  designed  to  address  a limitation in the obsolete LinuxThreads
       implementation whereby the  other  threads  of  an  application  are  not  automatically  terminated  (as
       POSIX.1-2001 requires) during execve(2).

       In the NPTL threading implementation, pthread_kill_other_threads_np() exists, but does nothing.  (Nothing
       needs to be done, because the implementation does the right thing during an execve(2).)
