Not necessarily. At some point, all the handling options could have been 
tried but all failed in which case there is nothing left to do except for 
letting something higher up (like the operating system) deal with the 
situation. In such a case, recovery did not occur if you consider 
recovery to mean that the program keeps running normally.

That sounds like the common misconception that leads to weak designs.
