| Sorry, you're right about the spawned process of course.

| the shell where the command is invoked. (However that is
| done, but I guess there is a C call for that.)
|
| So if you run 
| $ db2 login bla bla bla
|
| there will probably be something like below which wasn't there before
|
| $ echo $DB2_SESSION_ID (just guessing here)
| 123123123121

"db2" could do that only if it were a shell alias or function.
In general, your process environment is safe from the commands
you run, they can't touch it, and that applies to python programs.
