While this is generally ok, the problem is that all the consumers handle similar cases (and expect to catch) ENOSPC for this (for a reference look at minidumpsys() and dumpsys() constructions). That ends up in consumers not recognizing the issue and amd64 failing to retry if the number of pages grows up during minidump. Fix this by returning ENOSPC in dump_write() and while here add some more diagnostic on involved values.
