Hmm ... so if DrRacket adopts a different set of environment variables from 
command-line `racket` — which I assume is the correct and just policy — isn't 
that naturally going to lead to detectable differences, for a program that 
depends on those variables?

For instance, it seems odd that DrRacket agrees with `racket` on #"USER" and 
#"LOGNAME" being #"MB", but #"PATH" is totally different. 

In DrRacket it's #"/usr/bin:/bin:/usr/sbin:/sbin", but I don't know where that 
comes from. 

Moreover, suppose I had a racket shell script that depended on my user "PATH". 
I don't see how I could test that program in DrRacket without dropping a 
`(putenv PATH "my_user_path")` at the top.

We are in a maze of twisty little passages, all alike.

In this case I was trying to configure a web servlet to run in differently when 
launched from DrRacket (in terms of its port and servlet-path) to better 
approximate Apache / htaccess conditions that exist on the live web server.
