I am not an expert, but the construction (with Tcl 9.x) :

1) launch both processes in background

2) check the status with ::tcl::process

3) post-process the output of each process as soon as it has ended (*)

seems doable but no one mentions something similar, is this a construction 
to avoid ?

(*) with a monolithic script if it is fast, I mean no thread or 
different interpreters
