dup-btrees? i thought it's about psets..

pset is created for each instance of object with set-value slot, so there 
could be tons of them.

but dup-btrees are created only one per slot definition, so it's not 
critical.

or i've missed something and dup-btrees are created for each instance in 
some case?

btw, i haven't found any tests related to set-valued slots. do they exist?

yet.

if we want to improve allocation of psets, that should be fairly easy with 
single dup-btree
for all of them, and perhaps code will even be portable between cl-sql and 
postmodern.

but improving allocation of dup-btrees will be sort of challenging..
