# This is a FIFO Hash.  Why do I want a FIFO hash?  For eroding
# configurations, of course!!!  Just kidding.  This is to keep large
# dictionaries limited to often-used values.  When all the values can be
# calculated anyway, but a dictionary runs the risk of growing too large,
# this keeps the dictionary in check.
