Ok so lets move it to documentation if the docs are in error

I've added the following text to prctl(2) under the description of
PR_SET_PDEATHSIG:

              Warning:  the  "parent" in this case is considered to be
              the thread that created this process.  In  other  words,
              the  signal  will  be  sent  when that thread terminates
              (via, for example, pthread_exit(3)), rather  than  after
              all of the threads in the parent process terminate.

This suffices, I believe. If not, please reopen the bug.

Thanks,

Michael
