I did not word this carefully enough. The aligness is such that the zeros
appear at the end of the page.
For 4k zero bytes, a full page is filled with zeros.
For the one 2k zero bytes hole, the affected page is split into two even
parts, the first contains good data and the second zeros.
The 3*1024 zero bytes hole fill the last three 1024 byte parts of a page,
the first 1k is filled with good data.
