:: +by-clock: interface core for a cache using the clock replacement algorithm
::
:: Presents an interface for a mapping, but somewhat specialized, and with
:: stateful accessors. The clock's :depth parameter is used as the maximum
:: freshness that an entry can have. The standard clock algorithm has a depth
:: of 1, meaning that a single sweep of the arm will delete the entry. For
:: more scan resistance, :depth can be set to a higher number.
::
:: Internally, :clock maintains a :lookup of type
:: `(map key-type [val=val-type fresh=@ud])`, where :depth.clock is the
:: maximum value of :fresh. Looking up a key increments its freshness, and a
:: sweep of the clock arm decrements its freshness.
::
:: The clock arm is stored as :queue, which is a `(qeu key-type)`. The head
:: of the queue represents the position of the clock arm. New entries are
:: inserted at the tail of the queue. When the clock arm sweeps, it
:: pops the head off the queue. If the :fresh of the head's entry in :lookup
:: is 0, remove the entry from the mapping and replace it with the new entry.
:: Otherwise, decrement the entry's freshness, put it back at the tail of
:: the queue, and pop the next head off the queue and try again.
::
:: Cache entries must be immutable: a key cannot be overwritten with a new
:: value. This property is enforced for entries currently stored in the
:: cache, but it is not enforced for previously deleted entries, since we
:: no longer remember what that key's value was supposed to be.
