The ionice priority is similar to nice, but the levels nice values range
from 0 to 10, and unlike the usual nice, 10 is the highest priority and 0
the lowest. Usage is exactly the same as nice:
I think the principle of least surprise would suggest that it should 
work exactly like nice, rather than flip it around, or people will get 
confused why the misbehaving program continues to eat all IO even after 
they reniced it.  :-)
nice is actually intuitive - the higher the number, the 'nicer' the 
processes are to the rest of the system..

negative nice => "mean"

it's just *system* relative - not process relative..

perhaps a commentary on our modern individualistic nature, that we get 
this wrong..

or something..

shutting up now.
