The UFS and ext2 filesystem space allocation routines become very 
inefficient when free space gets too low, so for regular uses the 
filesystem is considered full before that threshold is reached. You can 
adjust the threshold setting (amon others) with tunefs.

Root uid processes can continue to use disk space after that point so 
that various daemon processes don't stop, and so that recovery actions 
can be taken.
