no.  it only holds the data for one row.    but, if you are creating 
lots and lots of objects, the cache may be getting very big.   after you 
are done with your objects (like at the bottom of your loop), within the 
plugin, call $self->undefPointerCache() to empty the cache.   See 
GUS::Rad::Plugin::ProcessResultLoader

you can create an object of the Other type by saying Other->new(hash) 
where the hash has the values you want to select on.   You will get back 
the first object that matches those values.   Then you can get the 
object's primary key.
