For some time, the writer has been using the AutoKey utility on their Linux computer to give them emacs-style keystrokes in web browsers and certain other programmes.
Recently, however, they have found that it sometimes stops working after a long period of use or after the computer has been asleep for a long time, and the standard repositories for their distro - KDE Neon - no longer carry it.
After some investigation, they found that AutoKey was occasionally consuming increasing amounts of memory until it became unresponsive, and they solved the problem by writing a wrapper script that monitored the memory consumption of AutoKey and killed and restarted it when it went over a certain threshold.
They used the /proc file system to find out how much memory a process is using, and built their script accordingly.
