OK, Roman, we've each had our say on how this circuit of yours will
behave, and our accounts are obviously at odds: you say it should be
"pretty efficient", and I say its efficiency will be exactly zero
because the circuit's just going to sit there doing nothing.  If it
oscillates at all, it will be at far too low an amplitude to be useful.

Since neither of our opinions on what this circuit "should" do counts
anywhere near as much as what it actually does, and since you were the
one to propose it to the PICLIST, how about you do us the courtesy of
building your circuit, testing it and reporting back to us with the
results.
