(...) Ahhh, this is a hint why it shows up now. The additional delay in the dsensor code shifts the duty cycle of the sensor down just a little bit, so it can't operate anymore. This will all be fixed with the new code in 0.2.5. I will get myself (...) (24 years ago, 27-Jul-00, to lugnet.robotics.rcx.legos)

OK, so I had forgotten that for whatever reason legOS rotation sensors are very, very sensitive to dying batteries.
