NOPL for synchronisation - of user space. I'd say thats sufficiently
unlikely not to care. It's still an improvement on crashing.

The other point you make is a good one but it's not clear that all the
proprietary apps for example will get recompiled, so to many users its
not a solution. Similarly the long term stable distros aren't going to
recompile everything and invalidate all their test data, so I doubt that
things like Centos will.
