+Linux only:

+libburn tries to avoid a collision with udev's drive examination by waiting
+0.1 seconds before opening the device file for a longer time, after udev
+might have been alarmed by drive scanning activities.
+The waiting time can be set at ./configure time with microsecond granularity.
+E.g. 2 seconds:
+  CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=2000000"
+  ./configure ...options...
+Closing and re-opening can be disabled by zero waiting time:
+  CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=0"
+Alternatively, libburn can try to be nice by opening the device file,
+closing it immediately, waiting, and only then opening it for real:
+  CFLAGS="$CFLAGS -DLibburn_udev_extra_open_cyclE"
