low-memory-monitor: new project announcement

I'll soon be flying to Greece for GUADEC but wanted to mention one of the things I worked on the past couple of weeks: the low-memory-monitor project is off the ground, though not production-ready.

low-memory-monitor, as its name implies, monitors the amount of free physical memory on the system and will shoot off signals to interested user-space applications, usually session managers, or sandboxing helpers, when that memory runs low, making it possible for applications to shrink their memory footprints before it's too late either to recover a usable system, or avoid taking a performance hit.

It's similar to Android's lowmemorykiller daemon, Facebook's oomd, Endless' psi-monitor, amongst others

Finally a GLib helper and a Flatpak portal are planned to make it easier for applications to use, with an API similar to iOS' or Android's.

Combined with work in Fedora to use zswap and remove the use of disk-backed swap, this should make most workstation uses more responsive and enjoyable.
