while this may be more prevelent now, this has always been a problem.
i think we need some way to steal pages for contig allocations. find
the largest segment that has owners you can steal from. i'm not sure
about the details. possibly a simple version that could still fail
would find r/o non-wired pages. a more complete version that was
able to clean dirty pages in the largest otherwise clean segment would
be useful but it depends on the user being able to sleep...
