Test the theory that some links can report an interrupt that is lost
if reported *after* the link is handled.

Add a second pass to re-check all links that have not been serviced in
the first pass. This filter is necessary as an interrupt will usually
generate a set of commands that are handled with, d'uh, interrupts.
