Things might have changed, but this certainly didn't used to be true of the
Pyramid system we had - st_blocks was in units of f_bsize. Things like "du"
gave results that were out by a factor of two (or more) depending on the
NFS filesystem that your files lived on! I agree with you that this was
wrong, but I have never seen the correct units actually stated anywhere.
