No, this is a different issue. The problem was not that the filesystem was
full, but that the fill rate was comparable to the amount of 'empty' space.

Yes, but if you fill up your root partition, there's nothing that can be
done. Full is full.
We're talking about the special case of small root partitions, such that
softupdates inability to make empty space available quickly can make the
difference between a major operation's success or failure.
This is almost impossible on a 1.8Gb root partition. And if you had a 1.8Gb
partition with only 15Mb free, the last thing you'd care about is how
softupdates will handle the situation.
