There's an article in the July EC magazine that talks about the new GFCI construction requirements. I was surprised to read that if these are miswired the button will pop out and they will not reset, (as we expected) but they will be energized?
On a miswired receptacle the power is applied to the "load" terminals and therefore directly to the receptacle face. To prevent this from happening a second set of disconnect contacts would be required after the receptacle face. A possible block diagram would then be:
I'm sure it's not as simple as it sounds, most things aren't.
It's a surprise to me though, I assumed claims that it 'would not reset' had something to do with denergizing the receptacle so it couldn't be used if there was no GFCI protection. Didn't everyone think that would be the case?

This sounds like the GFCI receptacles are single pole breaking only.
GFCI receptacles here in Sweden (and presumably in all of Europe) are double pole breaking. Portable GFCI's are also double pole breaking. (It can be turned either way in the receptacle and fits both grounded and ungrounded receptacles.)
How much does a GFCI receptacle cost in the US? A portable GFCI?
