Comment 109 for bug 159356

I've tried to set vm.min_free_kbytes to 6% of my total physical RAM, divided by the number of cores as it is said there https://askubuntu.com/questions/41778/computer-freezing-on-almost-full-ram-possibly-disk-cache-problem, but I decided to keep vm.swapiness at its default (60), because I was going to tune up zram.
And then I had installed zram-config package, opened /usr/bin/init-zram-swapping file with my text editor and had changed this string
mem=$(((totalmem / 2 / ${NRDEVICES}) * 1024))
to this:
mem=$(((totalmem / 2 / ${NRDEVICES}) * 5 * 1024))

Then I had rebooted and tested this all with "stress -m 4 --vm-bytes=1G".
This all was happening on my one core 2Gb x86 Lubuntu 16.04 notebook. Seems it works.
