I had a proposed patch that made udev write its sequence number to the kernel, and thus allowed any kobject add event to have a "bottom half" that could happen when udev had finished. The idea was that the existing ioctls could then just block. The other patch we tried a couple of releases ago was have devmapper spin until udev had caught up.
