Is it that difficult? A simple DB table with a timestamp, the region and 
the string, with possibly a combined index of timestamp and string 
should do it...

How do you track the validity of the strings right now? Is the timestamp 
coded in?

What number of hashes are we talking about?

*thinks* You could step through the list and do something like delete if 
rand()>1/((time(now)-time(string))/1800)...

That way, you have a 50% chance to delete the strings after one hour, 
75% after 2 hours, etc.

Would that be a performance problem? Anyway, if a location string is no 
longer in the DB, it's no longer valid - and the strings an adventurer 
remembers are a completely different beast... at that point, you don't 
have to check for validity... if it has expired already, too bad, the 
monsters moved. If the player entered the string from a piece of paper 
beside his keyboard, well - he mis-remembered... ;-)

Best regards,

Ulli
