Machines are going multicore, quad core is becoming common and in five years we'll probably have sixteen core machines. It would be good to use this: have thunar generate thumbnails in parallel.

This is actually an advantage to having thumbnailer scripts too: the file-manager just needs to launch them to the background: no need for a parallel-implementation of each individual thumbnailer like would be required if it were daemon-based.

I'm not sure if it's best to use all processors with a very high niceness, or use P-1 of them.

Reproducible: Always
