The space management algorithms in many file systems don't always perform well when they can't find a free block of the desired size. There's often a "cliff" where on average, once the file system is too full, performance drops off exponentially. UFS deals with this by reserving space explicitly to the root user (in the hope that the system administrator knows about the problem, and ordinary users can't trigger it). ZFS gives all the space to the user, which is good, but it means the user needs to avoid filling the file system "too much."
