 I hope so:-) Next time it would be nice to detect and fix such bugs
 in major release or in .1  ... we need a way how to motivate users to
 use -rc releases (t-shits, beers? ;-)

Yes, I know about it, but I'm able to reproduce this only on ppc, add
"sleep 10" to the test fixes the problem, so I guess that "udevadm
settle" is not so reliable on ppc.

Note that I'm working on new resize code, so this test will go away
and it will be replaced with separated "resize" test script.
