As far as I see the central question of the patch is the generic WebKit interface for parallel jobs. The technical details (which platfom how implements them) is secondary. The header contains a simple, portable interface, which has 3 steps:
 - request threads, passing the optimal number of threads
 - system returns with the number of allocated threads (always <= optimal, but >= l), 
 - fill the thread local data
 - execute the jobs, and wait for finish

Alexey, would you do that a different way? Again, the purpose of this work seems to find a simple, yet powerful parallel processing interface. The openmp thing is just an implementation, nothing more.
