I think this is a bug in softupdates that it doesn't reclaim > space quickly enough or in overflow situations. It's really not a bug, it's just a missing feature. There's no requirement that a filesystem reclaim empty space immediately. You really shouldn't be using fastupdates on nearly full filesystems -- it doesn't handle that situation particularly well. Once could even argue that it's preferable to force the make to abort than thrash the filesystem. Though a switch to allow it to thrash might be helpful in degenerate cases such as this. Fastupdates is great for the most common case -- a typical /usr or /home partition. That's where you care about write performance anyway.
