I was explicitely thinking of mutex and locks when I said the above. Is it
possible to do it in a model-independent way? My idea was to take as
fundation a well-established threading library and to build interfaces to
it. If we don't, sometimes we will have to go very low level, and this
will also carry a dependence on the O.S.

Opinions?
