This means that a table that was filled, then emptied, will have
performance for unsuccessful searches in O(hash->size)
- The solution here is to decide when the table is too full of deleted
- entries and recompute the data into a clean version of the hashtable.
+ This is worked around in practice by later inserts into a hash table
+ with many deletes in it triggering a rehash at the current size.
* The data pointer increases space consumption for the hash table by around
