Now that I've been pointed to the thread I can comment on it.

Yes, this approach makes a lot of sense. Programs which shared syn
objects without declaring them correctly are broken and deserve to
fail. It would be quite a lot of change in libpthread but it's
manageable.

I haven't tested the code nor will I likely do until I get a Fedora
kernel with it. So, convince DaveJ to take it for testing.
