If you want to give up, then give up, but then don't complain about the 
current behaviour.  If you want to fix it, then continue the discussion.

You're right that we're on different wavelengths.  If you want some 
tests to run at home but not on CRAN, then somewhere there has to be a 
conditional.  I'm suggesting that the conditional should be "if there's 
a tight time limit, skip this".

I don't remember if this was your suggestion, but someone has suggested 
"if we're running with the --as-cran option, skip this" and others have 
suggested "if we're running on CRAN, skip this".   I don't see why you 
find my suggestion so objectionable.  If you want, I'll repeat why I 
find the other two suggestions objectionable.
