statvfs(2) is standardized, but doesn't seem portable: it isn't 
available on OSX 10.3, NetBSD 2.0 or OpenBSD, for example. Perhaps you 
can fallback to statfs(2) when it is available?

This seems an area where providing consistent cross-platform behavior 
might be difficult. Do we actually need this functionality inside the 
DBMS in the first place?
