Windows XP eliminated must-succeed requests to make the system more stable. Suppose an enterprising programmer rewrote the operating system to accept must-succeed requests, but only when the system had enough main memory to fulfill the requests.What are the pitfalls of this policy?
What will be an ideal response?
Such a policy could allow a greedy or malicious program to circumvent Windows’s
localized LRU page swapping policy.A process could issue many unnecessary must-succeed
requests and fill all of main memory with its own pages, forcing the system to swap the pages
of other processes to disk.This would degrade performance.
