Approximative, because it's using our binlogging way (what we call "query"-level) and this is not as good as record-level binlog (5.1) would be. It imposes several limitations to routines, and has caveats (which I'll document, and for which the server will try to issue errors but that is not always possible). Reason I don't propagate caller info to the binlog as planned is that on master and slave users may be different; even with that some caveats would remain.
