I hadn't noticed that.  I will look for it next time I'm wading through the
compiler.  What I thought I saw was that a unit would request abc from
another unit, which would result not only in its parsing but in its
reduction to byte code which I would think you would want to avoid if you
are trying to sync everything up.
