Hi,
is this expected change in memory usage after your patch?:
(in init 5 stage, please note dipslayed the MemShared: memory value)

fresh boot with -ac15:

I have to say the -ac15+page_launder_patch kernel has turned on the extra debugging options
in Kernel hacking menu. Otherwise all kernel params are same with the -ac15.

I was not able to reproduce memeory allocation errors during 20h run
yesterday with -ac15 kernel using mysql tests and benchmarks.
I'll try to do same today with this patched -ac15 kernel.
