Comment (by karsten):

 I'd say let's add a warning if there's not much space left on the device
 at the beginning of a run (less than 200M?).  But let's not make CollecTor
 behave differently when it finds that it's low on disk space.  If we have
 such warnings in place (the Nagios notification and the new low-on-disk-
 space warning), we should assume that operators are smart enough to do the
 right thing.  The recent problems only happened, because we don't have any
 notifications at all.  But acting differently in case of low disk space
 would be like a car on reserve that doesn't let you drive faster than 100
 km/h or not in opposite direction of a nearby gas station.  Oh, I would
 hate a car that thinks it's smarter than I, even if it is.
