That is an excellent technique, and I don't recall having real problems
lifting the pin from the Vcc or GND holes (signal pins are easy) - I
recall having problems getting the power through-holes clean enough to
install a socket.

I think I had to resort to heating one side of the board and sucking the
solder from the other side - much easier with the board in a vise.
