Once again I don't understand. If the access pattern is not known, how do you
prevent simultaneous puts to the same region without a lock?
I should back up a bit...I don't feel passionately that the strict locking
semantics are the only possible solution. I really like the simplicity and
elegance of the model, but if there are compelling examples of codes that need
more flexibility then we should do our best to accomodate them. But I still
haven't seen many concrete examples (that I understand) which could not be
handled well by either the more restrictive lock semantics or a pure
