soft or weak

Wonder if we should go from WEAK to SOFT as a default policy for  
object retention in the ObjectStore. I just got a few annoying cases  
of objects being immediately gc'd after each request, so a new request  
looking them up by id finds them in the shared cache instead of local  
(somewhat slow) and then previously resolved to-many relationships are  
re-read anew (very slow).

Of course locally I just switched my ObjectContext factory service to  
use SOFT, so I am all set (I am yet to see it in production; wonder  
how that affects already slow major GC cycles). But I am wondering if  
that would make a better default policy for 3.1?
