I don’t know enough about X11 programming to be sure, but it probably needs to do this in order to catch modifier key state in events sent to other windows. Still, it is ridiculous to poll for events a thousand times a second. I think 10 times a second would be a more reasonable match for normal human response times. Turns out key-mon was written for Python 2 and GTK 2, and has not been maintained in a long time. I did some work on it as of today to update it to Python 3 and GTK 3, and the current state of my version is here <https://github.com/ldo/key-mon>. Almost certainly needs a bit more testing. At some point I might suggest replacing the Debian package with my version, if no-one else can offer anything better.
