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?
