I ran a similar test [1] on a 16GB Ubuntu box:
# uname -a Linux ubuntu-m-16gb-nyc3-01 4.4.0-45-generic #66-Ubuntu SMP Wed Oct 19 14:12:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
# cat /etc/issue Ubuntu 16.04.1 LTS
# history | grep wget 5 wget http://files.pharo.org/get-files/60/pharo-64.zip 6 wget http://files.pharo.org/sources/PharoV50.sources.zip 7 wget https://bintray.com/estebanlm/pharo-vm/download_file?file_ path=pharo-linux-x86_64threaded.0a4ccdf.zip
# ./bin/pharo -vm-display-null pharo-64.image st --quit memtest.st >& out.log &
Which gave the following (abbreviated) output:
uptime 0h0m0s memory 70,918,144 bytes old 61,966,112 bytes (87.4%) young 2,781,608 bytes (3.9000000000000004%)
I see yet another bad usage of round:/roundTo: --------------^ Ah, but it was another thread ;)

So, yes, it works on Linux too.

Ok, I'll try that in the coming days on my desktop box. I've got 32GB on that box, so it will be interesting.
What would be a good way to stress test the GC?

Only as a professional demo for code developped up to the very last moment on Pharo 32 bits. So I didn't try to explose the available RAM on my laptop (yet).
