Minchan,

It's much cleaner to keep the unchanged congestion_wait() and add a
congestion_wait_check() for converting problematic wait sites. The
too_many_isolated() wait is merely a protective mechanism, I won't
bother to improve it at the cost of more code.

This is what I've done. I dropped the patch again and am using
wait_iff_congested(). I left the too_many_isolated() callers as
congestion_wait().
