I got the recipe. Now my question becomes: How do I make sure an object
is completely in memory?

As far as I understood _any_ object should be serializeable via
TObject's Streamer method, right? Is there some way of telling a ROOT
standard object (like a TTree) "Hey, cleanup time. Get ready to be
streamed!" ?

Enlightening appreciated,

Andre
