True. Pure assignment will be lost, and is only ok for the case of a pure initializer (where nobody can see the old state). Your problem will be, of course, that any architecture that does this in hardware will just DoTheRightThing, and as such, broken architectures with bad locking primitives will have to test and do source-level analysis more.
