But as Andi said - look at all the crap involved when:

atomic_inc();
if (atomic_dec_and_test())
   release();
Also neatly captures that idiom.

And you get more flexibility by being able to use atomic_set
directly too.


But if you really like it, I agree it shouldn't allow NULL
pointers and probably get, put and cleanup should be inline.
