I have seen this:

Walter (from a comment written by someone else):

>A critical program, such as life support machines, flight control  systems, etc., cannot be allowed to fail.<

Such software most probably works with a fixed amount of memory (or at compile time it's known the maximum amount of memory required), so that's not an example where recovering from out-of-bound errors is important.


>The memory manager can have user supplied callbacks to release memory in such cases.<

This is interesting. What's a possible API/semantics for such thing?
