That branch is mostly there for historical reasons. I keep that branch as a
think-tank, but it is is obsoleted. Also, in less polite words than David
used, it simply doesn't work. Getting this code with multiple producers and
consumers correct is far from being trivial and the literature I browsed
indicates that it is probably not possible given the other predicates the
code must obey to. Still, optimization is high up on the todo list.
