FYI, I've been running with this patch installed on my 4-STABLE box for
almost four days now (would have been longer except for a power outage).
This is much longer than any of my previous uptimes since this problem
started occurring (which were generally on the order of a day or so), so
I have at least a warm fuzzy feeling about the code now.

Bruce.
