The slowdown is likely to be realated to a few specific debug options
such as debugging for mutexes, spinlocks, lists, etc. I guess that the
most interesting information would be a difference in the debug options
between the general kernel and the debug kernel. Hopefully we can put
together a set of debug options that are cause the test to run over
slow.
