it depends on the architechture, the variance in paths and attributes,
and how much your policy alters those, what is being sent vs filtered,
AND the number of peers and add-path, etc etc.  eg: if your policy
alters attributes, space for both the old and new attributes is needed.

Whether you need 64bit depends on the total memory usage exceeding,
iirc, 3.2GB.
