Generally I do not like if a program eats up all computing power without 
being told so. E.g. my machine has 8 hyperthreads but only 4 cores. 
Running on 8 processes hardly gives maximum efficiency, most oftenly speed 
is maximal at 3 processes. I also like the idea to use the remaining 
computing power for different tasks. Please just leave the choice of the 
number of processes to the user.
