you may be right.. I plan to examine stats over the next week as part of 
the kernel threads work.
I may be able to improve the situation.

my aim is that for threads that are doing M:N work the stats will 
accumulate on the thread
for a short while and then be collected to the KSEG when ther eis reason 
to think that
the kernel thread has changed purpose or exits (both of which happen a 
lot in KSE).

for 1:1 threads, they will continue to accumulate on the thread, since 
no "KSE events" will
occur.

The KSEGRPs stats will be collected to the process when asked for.
I will probably also change the way that 'ps' shows these (and threads). 
I'm not sure what to do about top yet. we really need to be able to show a
process name AND a thread name when the threads are shown and have names.
