------- Additional Comments from Gabor Loki <loki at webkit.org>
I have redesigned the previous concept of threading from Zoltan's suggestion
and introduced a framework for parallel tasks/jobs.

The ParallelJobs framework is based on WebKit's threading infrastructure and/or
OpenMP's API.

The usage of ParallelJobs is the following:
1.- Create ParallelJobs object - which allocates the worker threads and
necessary objects.
2.- Fill the parameter array - allocated by ParallelJobs, assign different
sub-tasks for the workers
3.- Execute the workers
4.- Combine the necessary information [optional]

This patch contains:
1.- ParallelJobs framework
2.- SMP version of FETurbulence

One more note:
I have measured 60%-80% performance progression on dual-core systems on ARM and
x86 as well.
