To this end they needed to patch CGAL to achieve thread safety forSounds very cool. The lack of thread safeness is a major concern for us
the Exact_predicates_exact_constructions_kernel. Now I'd like to
contribute this patch and possibly start a discussion about it:
(OpenSCAD) when using CGAL.
I’m not familiar with the inner workings of the shared objects in CGAL, but
do you think your patch will make it possible to execute multiple Nef
polyhedron CSG operations in parallel (i.e. multiple threads reading from the
same operands but producing different output) ?
Kind Regards,

The patch makes the basic number type thread safe, i.e. parallel
operations on basic objects (Point, Segment, Plane, ...) like
orientation tests and intersections will work now. I don't know
the NEF package very well but maybe it benefits.
