Ooops! Fixed and the new patch contains some extra controls I've
discussed with Lennart in icecream.service:
    Restart=on-abort
    Nice=5
    OOMScoreAdjust=500
    CPUSchedulingPolicy=batch

This will be nicer with the actual users of the machine, killing
iceccd before most stuff on out-of-memory conditions, schedule it as a
batch work to not interfere with interactive tasks and restart if it
crashed (maybe due the above settings).  Of course, if there are no
other users and the machine is used exclusively as an icecream node it
should not impact as everybody will have the same values :-)

I really would like to set the capabilities to reduce the harm that
such thing could make, but as it's a trial and error process, I can't
do it now :-/

Anyway, consider the new patch!
