Currently, there is no obvious description in IMPLEMENTATION for
distinguishing the lost pages resulted by ENOSPACE errors or others.
So, it is added.

The page header and page data are written in pairs. When writing page data
(pfn N+1), if ENOSPACE error happens, the page headers after N won't be
written either.
+ When reading page from incomplete core, only the page lost by ENOSPACE errors
+ has 0 in its corresponding page descriptor's member offset.
If there is no page data dumped into the DUMPFILE, the DUMPFILE can't be
analysed by crash.
