OK.

You don't need a modification to tcpsvd to do what you want, however. You 
can write 'uuid', which generates a uuid, puts in in an environment 
variable, prints a message, then execs the rest of its command line 
arguments. Then instead of having 'prog ...' in your run script, you have 
'uuid prog ...'.
