# Let's get both processes loaded:
simto	4
show	1000
show	1001
show	pmt
show	fmt
#
# Run through a few page faults for each process:
simto	10
show
show	1000
show	1001
#
# And run through a few more. Process 1000 should reach its frame
# allocation limit by time 18:
simto	18
show
show	1000
show	1001
#
# The next page fault for process 1000 should trigger a page replacement:
simto	22
show	
show	1000
show	1001
#
# Now run for awhile and see what happens:
simto	36
show
show	1000
show	1001
show	pmt
show	fmt
#
# Run a bit further. This should be interesting due to the fact that
# some of the loaded pages have been re-hit, so the LRU page selection
# should show up now in interesting ways.
