that bug was a brain lapse on my part, but this was part of it. thanks  
for the fix!

(the bug was my code -- in my JsonRestStore subclass I support query  
in the format of

{foo:['a', 'b']}

where 'a' and 'b' are OR'd in the search.

so I had to override querySuperSet, matchesQuery, and isMatch for this  
case. Well, when passing a
string id as the 'query' for clientFetch, it checks querySuperSet,  
which fails in the default querySuperSet. But my over-ridden class  
fail right, so it caused a cache-hit. Anway, alls well that ends well.
