update_or_create is a row-level operation that gets performed in the 
context of a resultset; $rs->delete is a resultset-level operation. I 
don't see any particular reason not to support ->delete($cond) though 
(probably by just expanding it internally to ->search($cond)->delete), 
but somebody else gets to write up the test cases and patch :)
