Hi Pekka.

Are you talking about this old bug that broke the pipe?
If so, you fixed it yourself partially with a patch that corrected
tracing_read_pipe.
Another origin was the none tracer that set tracer_enabled to 0.
But i has been fixed with the nop tracer.

Perhaps you are talking of something else?
