What fact?  The only thing that matters is USB?  For resume, it is.  For
suspend, it clearly isn't.

I said I was going to use it, but I don't think that's going to be sufficient.

[BTW, I'm not sure what you want to achieve by insulting me.  Either you may
want to scare me, but I'm not scared, or you may want to try to make me so
disgusted that I'll just give up and back off, but this is not going to happen
either.]

Insults aside, I'm going to make some measurements to see how much time we can
save.
