Using the lucid kernel, I was able to reproduce, though it took a lot longer than original report implied, easily over an hour, probably more than 3 I wasn't watching it the entire time.
multipath-tools 0.4.8-14ubuntu4.10.04.2 kernel 2.6.32-41-generic
udevadm monitor simply stops responding.
I cannot remove the dm maps, they say "busy/in use". They are not mounted or used by anyone.
Using the same kernel and multipath 0.4.9-3ubuntu5 I was unable to reproduce the issue. So this older kernel helps expose the problem.
