We are simply incapable of doing anything in a simple way.
I see James' point but I disagree with his implementation.
I would recommend setting the refcount to 1 on allocate and doing just

If you are doing this because you presume the mutex might be shared with other
internals, then you *really* need to make sure the initial refcount is 1. And
if you do that, you shouldn't check for 0 (in fact, you should sdk_assert() the
ref count is > 0).
As a side note, I utterly fail to see the point of REF_COUNT_OBJ_REFCOUNT_DEC
as other than to be discarded as soon as possible legacy cruft.
