We allocate 128 pages for each "packet".
But we can ben handled less than that (we are at the end of one
iteration, the end of a ramblock, ...).
That is what used mean.

But later on the series, we enter with normal pages, and zero pages, and
naming get really confusing.  So, I moved to use *_num for everything.

Even after all the series, I didn't rename everything on multifd, only
the fields that I have to use sooner or later.

Later, Juan.
