As of CGAL-4.4, it is not. In CGAL-4.5-beta1, that will be published in a few 
weeks, there will be an experimental new feature: parallelization of 
Triangulation_3, using Intel TBB.

But, even in CGAL-4.5, the Delaunay_triangulation_3 will still not be thread-
safe: 
  - there will be new tools, such as a locking strategy, that will allow 
write 
parallel algorithms,
  - there will be new thread-safe functions, such as locate(), that are less 
efficient that the non-thread-safe one.
