Well, is it? I tend to think about it like "select", and "select for update" in
SQL, although the analogy is not 100 % correct, I know. But I intended
vg_read_for_update as a convenience function that obviously points out that you
intend to update the VG (as opposed to just read it).

But, I suppose it's a bikeshed point. We however still want a generic vg_read,
for the iterator functions (in toollib) which need to pass a flag to
differentiate the read/write case.

Yours,
   Petr.
