chmod is one(1) system call, while system is many, for starters it's
fork/exec, which btw, is quiet expensive, haven't counted, but my gut feeling
it's in the 10s.
So, if the program does this chmod once in a blue moon, there is no real
argument, but if id does it many times, then one system call is a real winner,
