I think the issue is that it's it's _possible_ that a out-of-control process could suddenly eat up a bunch of memory and go to swap right at the wrong time. If there's enough space, this is unlikely in practical use. I'm not super worried, because realistically that out-of-control processes and runaway swap thrashing was going to take your system down or at the very least trigger OOM killing *anyway*. -- Matthew Miller <mattdm@xxxxxxxxxxxxxxxxx> Fedora Project Leader _______________________________________________ desktop mailing list -- desktop@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to desktop-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/desktop@xxxxxxxxxxxxxxxxxxxxxxx
