I plan on adding parallel processing support into the gimp core.  The system I
will be developing this on is a 20+ processor box so I was planning on just
leaving a couple of processors idle for background tasks rather than doing any
kind of system load heuristics.

Mostly I will be working on paralellizing the pixel_region_process calls (each
tile potentially gets it's own thread), but I will leave hooks to speed up other
types of algorithms.

I won't be able to start this for a couple months, so if you or anyone else wants
this put in sooner please feel free to code it yourself.
