Change the niceness option to also ionice SExtractor

[mtewes]

Or add a separate ioniceness. In any case, ionice is in fact more important that nice...

[kuntzer]

What's ioniceness ? :)

[mtewes]

It's like niceness, but for I/O access instead of CPU.
I thought that the priority of I/O access was lowered by nice (nice including ionice somehow), but I was completely wrong (thanks Hendrik!).
So ionice is indeed more relevant than nice for sewpy.

[mtewes]

BTW did you notice how much "nicer" the doc now looks :)

[reikonakajima]

Wow, never heard of ioniceness before. Good to know.

[mtewes]

BTW the user command is called ionice. The word ioniceness might have just been invented in this thread...
