They are not supposed to debug a (very subtle) part of the code they do 
not understand.

That's not possible.  You would understand that if you had read the post 
upthread in which I describe in every detail what that variable does and 
why.  But you don't care, apparently.

That variable was added because Eli asked for it, to help debugging future 
problems in that (very subtle) area on the code.  But I already said that 
three or four times, and you don't care, apparently.
