Arduino Ethernet, Motor shields, probably other come with these extra-long solder tails
on their female sockets. Long enough that shields end up with good clearance over the
USB jack. Lone enough that you can plug an ISP plug into the Arduino with a shield on
top of it.
Adafruit/sparkfun etc. all sell lame version with shorter tails. Where can I get the sockets
that the smart Europeans use? 
I believe you need to find a part number at Samtec.com
Then find someone that carries them.

I think PC104 Plus might be the correct series, if not then ask them.
Can also request some free samples.
So perhaps ESQ-108-39-(LGT)-S
for single row of 8 pins, standard size receptacle, and the longest 0.025" square leads available.
LGT is the plating finish - see the drawing.
Check the drawing to see if that's long enough for you.

Thanks. It looks like they also have sockets where the plastic body (part above the board) is a bit longer than what's on the Uno Rev3. Maybe the next hardware rev shoud use a taller block. This issue has caused me trouble a couple times now, once with a
protoboard shield that hits the usb jack and so ended up having a flaky power connection, and again when I want to use ISP with
shields on. I don't think saving 2.5 or 4mm of height on the stack is worth the trouble myself, for a prototyping system in particular
the extra space between layers is more valuable.
