Parallel processing

I tried parallel processing for pdx. This means to generate the output files each in a separate thread of execution in parallel to save some time. But indeed and whatever I did I could not measure any improvements. The separate threads have to synchronize again and again which makes them wait on each other. The technology of caching selection results in memory (command line option -f) is much faster even if all the output is generated one by one. So I will not implement parallel processing in the next future.
