That's not really possible.  We can't rely on the visibility of symbol 
bindings due to lazy binding and hidden visibility.  Registration of 
intent by other means will not work because if it is done from user 
code, some other library may have already launched a thread at this point.

(It's also a moot point if we want to use restartable sequences in glibc 
itself.)

Thanks,
Florian
