 Description   

We report those regions as non-mapped virtual memory in serverStatus and thus in MMS, which can make the memory graph look scary unnecessarily, as these regions take up very little resources and shouldn't have any negative impact on a running server.

These blocks can be recognized by the protection bits '---p' in /proc/PID/maps and smaps. They should also have a 0 kB Rss.
