Nice setup - I wish more people did that!  Can I just ask a Really
Dumb Question: *exactly* when does this grab the stats?  Does it wait
for the response, or does it start gathering as soon as it's aware of
a problem (say, at 1 second)?  At the moment, for example, jstack
might not be showing anything because you're gathering data after the
call has completed.
