In addition to these, would it make sense for the REPL banner in the 
Interactions pane to indicate when DrRacket debugging and profiling are on?

This would be a hint to people about some of the common parameters 
affecting performance, along with Racket version, memory limit, GC, 
JIT,general platform, CPU arch, and maybe number of cores Racket knows 
about.

When showing the run of some timed code on the email list, we can even 
copy&paste this banner with it, as a quick way to convey some of the 
pertinent parameters of our setup.

Maybe don't show this info in student languages, but show it everywhere 
else.
