-The following is a demonstration of the anonpgpid.d script,

-Here we run it on a system that is implementing memory caps using the
-resource capping daemon, "rcapd",

-The "memleak.pl" process consumes memory, and we can see above that it has
-encountered both reads and writes to the physical swap device - it is being
-paged out. A bash shell was also effected (which was in the same project that
-rcapd was monitoring).

-The "pageout" process is responsible for writing all the anonymous memory
-pages to the physical swap device, and we can see from the above that it
-has written 23 Mb. When processes access anonymous memory that has been
-swapped out, a major fault occurs and the memory is paged back in; in this
-case we can trace the process that was effected, and from the above we can
-see that several processes have been effected by the memory pressure.
-The most is "svc.configd", which needed to page back in 1.4 Mb of anonymous
-memory.
-
-
-
-Sometimes anonpgpid.d doesn't help too much. Here we only have pageouts
-to the physical swap device and no pageins,

-Only pageout is identified.
