MINOR: pool: make pool_is_crowded() always true when no shared pools are used
This function is used to know whether the shared pools are full or if we
can store more objects in them. Right now it cannot be used in a generic
way because when shared pools are not used it will return false, letting
one think pools can accept objects. Let's make one variant for each build
model.
