what are the current plans for supporting atomic_* free functions for

there are multiple readers and single writer.

I've been thinking about it recently and am probably just going to
implement it with a single global mutex used for all shared_ptr
instances.


erm, but that would be even worse than using mutexes as in my example code ....
