It sounds like most people say it's not necessary.  But I have a suggestion I heard
somewhere for those situations when it is necessary.

If you made slot in a deep stock as you describe to get a stuck O2 sensor out, you can keep
the socket from spreading by putting a metal hose clamp on the bottom of it after you slip it
over the sensor, under the wire in the slot.  Otherwise, the socket might break.
