I really don't feel it is appropriate to use the term "lock free" to refer to an algorithm that requires locked instructions.
@rygorous I don't think this is generally true. Even on X86, this was not true on Pentium et al.

@rygorous The LOCK prefix was an actual system bus lock. Later, they made it so that it didn't have to lock if the core had it in cache. -
@rygorous But I believe it _still_ took the system lock if it wasn't in the cache after that (P4 and up). Not sure about _now_. - Show replies
