<p>Note that in cases where none of the atomic intrinsics are used, this model

for single-threaded execution: introducing a store to a byte which might not

<!-- FIXME: This model assumes all targets where concurrency is relevant have
a byte-size store which doesn't affect adjacent bytes. As far as I can tell,
