practically close to none, that's because some internals of tm that make 
such code run anyhow.

When tm is loaded it registers a function that is executed for each 
reply (even no onreply_route is there, it needs to update transaction 
state). The code to detect if there is a corresponding transaction is 
the same there as in t_check_trans() now. I added some extra attributes 
so subsequent calls of this code returns quickly if transaction was found.

default onreply_route is executed before tm onreply routes, so if you 
drop it in default onreply_route then no TM execution happens.
