Along with that question, what is the use case for this feature? The only
benefit mentioned was saving a few bytes of memory, at the cost of carrying
extra network headers. Atomics are only 64-bits to begin with...
For some applications the memory savings are very significant. One
example is fine grain lock implementations for huge data sets. In other
cases, the benefit is the ability to update multiple fields with a
single io operation.
