Add EmergencyClean mode

In this mode we are nearly full.
Cleaning just goes for the segment with the most space
even if it is quite new.
Allocation failures return ENOSPC rather than EAGAIN
We clean even if it doesn't look like it will help much.

The heuristic for switching in an out is rather odd...
