Just because a client has a reference to an EJBObject that is associated
with an object identity (=primary key), does not imply that the actual
object is activated in memory. On the contrary. It is much more likely
that at any point in time clients (as a whole) will hold, for example,
1000 references to different EJBObjects but only about 100 of those are
activated. This includes when a client has called a finder method: the
client receives EJBObjects referencing the found objects, BUT the
objects are not activated until you actually call the objects. And for
each object there is then two possibilities: it is already activated or
it needs to be activated. All discussions sofar has been using the
second scenario. But if a server uses a LRU eviction scheme it is likely
that commonly used objects are activated so there wont be too much
overhead with calling them.

Oh dear, yes I have been bogged with school stuff lately (my last exams
*ever* are approaching fast.. whee..), but this summer (minus JavaOne+US
trip) I'll work on XS to support EJB1.1 and lots more docs (and
tutorials). But there's only me here so time is limited.
