The old loop would run for exactly 300ms, and then use the uevents
generated during that time. 300ms might not be long enough if it's on a
physical network link (our tests are VM only). However, we also need to
still support more than 1 LUN.
I'm not sure how to find out how many LUNs there are going to be
beforehand, so we don't know how many devices we are looking for.
So for now, we do the following: we keep looping to find matches, until
we're reasonably sure that no new ones are coming. We time out after 3
seconds, which any caller can change.
