Hmm, this will suffer from TOCTOU issues, but I don't think those
should be overly problematic unless the user expects exact behavior
(which I don't think they will). Also, you should be aware that the
Win32 call takes disk quotas into account, so it may not report
accurate values for total disk space availability (which is the
correct behavior for your use case, but may not be obvious for the
caller of the fs function).
Win32 bits LGTM with that in mind.
