just thinking of it -- if you do t_newtran() before t_relay(), isn't it 
getting to failure route?

Perhaps it can be done (eventually with a modparam) for the case when 
the transaction structure can be created, but not when that fails (e.g., 
out of shared memory). These callbacks require transaction structure, if 
that is not available I expect it's going to require quite some changes 
in many places, not only tm module.

Cheers,
Daniel
