Aaron and I talked on IRC, and after some talking these patches
now make sense to me :)

The kernel apparently limits how many hung task warnings it
will display at a time, when a timeout occurs.  Aaron's patch
allows that limit to be set to "unlimited", which will cause
the kernel to display info about all hung tasks.
