There are software algorithms for mutual exclusion which don't rely on
read-modify-write instructions, like Dekker's or Lamport's algorithms.
Dekker's doesn't work with non-sequential memory model, but processors
which reorder memory access usually have read-modify-write instructions,
so it's not an issue.
