Version 8.3.3

Further reading gives me the impression that datasize is a limit but 
doesn't cause any older records to be dropped when its reached.  It 
just runs out of space.  It looks like that won't do what I want.  I 
suspect I need to find some way to make the cache have a max retention 
time that I can specify for retrieved records.  I haven't found such a 
thing yet.
