With the debugging code removed it doesnt look all that complex. Do you think i can attempt to plug this into the -RT tree, or should i wait some more? (One observation: if you know some branch is slowpath in a common codepath then it's useful to mark the condition via unlikely(). That results in better code layout and is also a guidance for the casual reader of the code.) Ingo
