So you'd go for the amount being used (as per the description) rather than the amount free (as per the name)? The current code actually implements this the other way round, i.e. reports the amount free. I'd be happy to switch over, but would strongly agree that we must clarify the situation before releasing 5.4.

That's an open question - I really don't have a feel for how straightforward it would be to calculate these values. My gut reaction is to stick with "free" - if only because this information is typically relatively easy to retrieve, without needing a deep knowledge of the O/S internals. But I'm lazy like that!
