PS2, Line 123: buffer
buffer from a clean page?

Should it also be plural, since we might have to reclaim multiple buffers if 
the new buffer is larger, right?


PS2, Line 178: .
... given our choice of eviction policy.

PS2, Line 446: Make sure that we have enough space in the reservation

Line 467:   // Make sure that we have enough space in the reservation to do so.
