Too bad, bad we don't have control over all the udev rules out there
doing that, which will dead-lock then. And too bad that when udev
calls modprobe we still don't solve the races. Too bad that calling
"settle" waits for all events and you can never know when loading a
module what to wait for and what not. It's just not a close to a
solution that is doing any good. What's the point of all these weird
workarounds you are proposing? I think it's properly solved already.

Thanks,
Kay
