Question regarding nullified relationship objects

Namaste!

If I have two entities, A and B, where A <-->>B, and the delete rule in
entity A's relationship to B is cascade, and B's delete rule for the
relationship to A is nullify, what happens to the actual "row" that holds
the relationship data in A that was once B after B is deleted?  Does it get
completely deleted, or is it left as garbage that is later cleaned up, or is
left and later re-filled?

Thanks!

Peace, Love, and Light,

/s/ Jon C. Munson II

P.S.  Thanks to mmalc for posting a comment in another post that led me to
the Relationship Delete Rules section of the documentation.
