I'm guessing since Chris mentioned linuxthreads that you were depending on
non conforming behavior (i.e. incorrect) from linuxthreads.   You can't
depend on NPTL being broken in that way.  You need to learn to do pthreads
programming correctly.  However we can't give you any suggestions or hints
since you still haven't told us what you are trying to do.
