Memory usage doubles on reload

[PetrHolik]

Ok, thanks for info.

I'll, do some research. I read some articles about memory allocation and I
think when the system will be going to out of memory, the will try to
reclaim freed pages which in normal situations when have enough ram does not
because of avoiding memory fragmentation.
