X11 screen lockers are not secure at all if you can get them to crash in any way, they revert to showing the full desktop unprotected.

This isn't quite true. There are some X11 screen lockers (maybe only GNOME?) that coordinate with the login manager so that a crash just leads to a restarted login manager.

...but yes, most X11 screen lockers have this flaw.
