I think libstoreio and devprobe should close the device. Thanks for
reporting this, I will look into it (I think with what you said, the fix is
pretty straight forward, but I want to test anyway).
One problem is certainly if you kill the task that opened the device without
giving it a chance for proper shut down. Then the door remains locked. I
don't know if Mach can detect it, but it would be a good idea. If anybody
can work on that, do it!
Thanks,
Marcus
