Differentiate hash table/ frozen and manual/ normal completion

Adding and looking up items based on a hash table is incredibly
fast, so it's vital for startup, however at runtime we want
to prepend which invalidates the contents of the hash table. So
now we use the hash based lookup only for frozen operation,
which is used at startup and has to be fast, but manual string
comparisons are used at runtime.
