Now, I'm all for blaming Microsoft for their multitude of screwups, but this is really just a design issue, and it's perfectly consistent behavior.  <ALT>-<F4> is supposed to be handled by the application, but <ALT>-<TAB> and <CTRL>-<ALT>-<DEL> are system-level commands that get handled by the OS.  If you press those keystrokes, SDL will probably generate the appropriate keypress event, but since the handler's registered at the OS level and not the application level, you don't see any blocking behavior.  <ALT>-<F4>, on the other hand, is a menu shortcut that has to be handled by the application.
