I didn't intend to imply that core data structures had to be lock free,
it is clear that creators of thread and process safe data structures
should be free to use locks if it makes things faster and more
efficient. My point was about applications built on the language
platform: the platform should provide all the things needed so that
applications code never mention locks.
