In Ubuntu 16.04 if you run
perl -e 'sub x { x() }; x()'
(this commands does a deep recursion, eats all memory)
under non-root user
whole system becomes unresponsive, mouse, keyboard does not work. Screen does not update when you plug/unplug charger, for example. The only way to quit is to press power button and shut down machine.
Expected bahaviour: Ctrl-C, Ctrl-Alt-Del, Ctrl-Alt-F1, mouse, at least something should work.
Repsoduced on HP Pavilion 16, SSD with encryption, encrypted Swap. Reproduced by at least one another person with Ubuntu 16.04 with SSD.
