Suppose that two processes $A$ and $B$ share a page that is not in memory. If process $A$ faults on the shared page, the page table entry for process $A$ must be updated once the page is read into memory.

  1. Under what conditions should the page table update for process $B$ be delayed even though the handling of process $A’s$ page fault will bring the shared page into memory? Explain.
  2.  What is the potential cost of delaying the page table update?
