+1, especially since the kernel is not special; anyone working with
threads faces the same issues in userland, which are often hidden
behind the implicit whole-memory clobbers of certain operations or
the call to mutex manipulation functions, but which become a reality
again as soon as you go slightly away from these and try to use
lockless mechanisms.
