# Each command prints the current state of the buffer pool.

#
|
|
# [ ] - Indicates a cell within BufferPool.pool's underlying array that's
|
|
# unused and does not hold a buffer.
|
|
# [ n] - Indicates a cell within BufferPool.pool that is not currently in use,
|
|
# but does hold a buffer of size n.
|
|
# < n> - Indicates a cell within BufferPool.pool that holds a buffer of size
|
|
# n, and that buffer is presently in-use and ineligible for reuse.
