The other thread deals with this issue extensively, pointing > out why I claim it's "nigh unto impossible". In a multitasking > environment one can NOT fully protect an application from memory ^^^^^ You just raised the bar. Your initial claim was that it was nearly impossible to recover from memory allocation failures; such a claim could be refuted by demonstrating an method that recovered from 10% of all such failures. However, even a method that recovered from 99.9% of all such failures wouldn't meet your new standard, since the remaining 0.1% of the case indicate that it's not fully protected.
