Why might a global page-replacement policy (in which an incoming page may replace a page of any process) be more susceptible to thrashing than a local page-replacement policy (in which an incoming page may replace only a page belonging to the same process)?

What will be an ideal response?


The global strategy could overreact to the poor behavior of one process by stealing
page frames from well-behaved processes.A local strategy would guarantee reasonable service
to well-behaved processes, while the poorly behaving process would be confined to live
within its own allocated number of pages whether it thrashed or not.
