Hi H2 Group,

I am trying to take advantage of the query cache, but I am getting some 
unexpected results (h2-1.3.173.jar)

In a single session, if I run a query A, and then repeat the query A, the 
second result is returned very fast (0-1 ms).

However, if I run query A, then query B, and then query A again, the result 
for A is not returned that much faster than the first time.  I would have 
expected the results of A (which are rather small) to still be cached, as 
the default is 8 results in the query cache (if I have understood it 
correctly).  It seems as though only one result set is ever cached.  Any 
thoughts? 

Here is some info about my setup: embedded mode, close_delay=-1, using 
prepared statements.

On a similar note, it seems like a global query cache, as opposed to a 
separate one for each session, would be useful. 

Thanks,
-Adam
