Looking good! Thank you.

I have tries all 3 possible values, and the behavior looks as expected. 
With 't', I even see a small delay when launching the process,

I haven't been able to verify that the debuginfo stuff is actually 
working (nor sure where to look), but the basic functionality is now okay.
