I've just updated
simple_parallel so that (some of) it compiles against 1.0.
Unfortunately, a lot of the API uses
std::thread::scoped internally (so I've had to disable them), or suffers from the same
unsafe problems as
scoped (so I've had to mark it
unsafe). In fact the only thing left "undamaged" is
Pool::for_, but that still might be useful.
(You can get full gamut of the old functionality with the
unstable feature and a nightly compiler.)
