Old engineer's maxim: "Oscillators amplify, amplifiers oscillate, and Murphy always wins."

In the circuit above:

a) All three resistors are equal.
b) The op-amp is compensated to be unity-gain stable.
c) The battery is exactly 1V.

Questions:

1. Is this circuit stable or does it oscillate? Why?
2. If is stable, what is the output voltage?
