As a consequence of trying htop after a long time, I got a reminder that VIRT is not related to RES. I noticed Libreoffice Calc with 29.7 GB of virtual memory and only 198 MB actually used. I wonder why LO made a malloc of nearly 30 GB, but memory is cheap especially because it's virtual.

The next one on the list is Firefox with 8.5 GB VIRT and 994 MB RES.

By the way, I've got 16 GB of RAM and no swap. Anyway all that empty memory between VIRT and RES doesn't go to swap, it's really virtual.
