[Levente Uzonyi]

Ubuntu 20.04.4 LTS. Start the image and watch as the resident set size 
grows indefinitely:

$ watch ps -C squeak -o rss

You may prefer htop over watch+ps.

>> Affected VMs include: 5.0-202206021410, 5.0-202205110711, 5.0-202204190959
>> Unaffected VMs include: 5.0-202112022203 and 5.0-202112201228
>> The 5.0-202206021410 assert and debug VMs leak the memory as well.
