When pressed too quickly multiple times, Ctrl+Shift+Y may delete more lines than desired

[michaelkonecny]

If I press Ctrl+Shift+Y twice very quickly, three lines get sometimes deleted instead of two.

Seems like the first deletion operation wasn't finished when the second keypress occurred and they intervene somehow (probably the text selection gets messed up).

This should be debugged, if the above is the cause, some sort of queue should be created, to make sure only one deletion operation is running at a time.

I'm not sure how to fix this.
