What, exactly, are stat.st_blocks, statfs.f_bsize?

Methinks the stench comes from POSIX, which gutlessly refused
to buck existing but ancient practice. I assume that's why BSD changed.

Oddly enuf, this came at a time when 1K FS blocks were becoming
more common in System V. It is a fortunate coincidence that
2^10 ~= 10^3. Too important not to take advantage of.

I was delighted when Berkeley "defined" a "block" as 1K. No more
doubling or halving in one's head when trying convert blocks to chars.

To make it worse, Pyramid's FS block sizes are 2K to 16K (yes, the
sectors are 2K), and so they report blocks in 2K increments. It is
rather sad to see filesystems quadruple in size when reported
between NFS partitions mounted to or from a Pyramid. Oh well...
