Plans:

Make statprof use generic stat collecting machinery, doing something like:

def profile_signal_handler(signum, frame):
    if state.profile_level > 0:
        record_absolute_sample(seconds=clock())
        itimer.setitimer(itimer.ITIMER_PROF,
            state.sample_interval, 0.0)
        # so we would skip any data changes that happen in the stat collector itself!
        set_absolute_counter(seconds=clock())

instead of this:

def profile_signal_handler(signum, frame):
    if state.profile_level > 0:
        state.accumulate_time(clock())
        sample_stack_procs(frame)
        itimer.setitimer(itimer.ITIMER_PROF,
            state.sample_interval, 0.0)
        state.last_start_time = clock()

So I'll have to have 2 different stat recorders, the current:

record_sample(counter1=delta1, counter2=delta2)

and one more:

record_absolute_sample(counter1=value1, counter2=value2)
set_absolute_sample(counter1=value1, counter2=value2)

that would use the difference between the old value and the value
being recorded as a parameter to the record_sample function

Also display function has to be modified so that statprof profiler
could do:

def display():
    from nous.pystat import display
    display('seconds')

to get the current view. Don't know what to do with the "we have 20
counters" display yet, the current "use the total of record_sample
calls number for default ordering" kind of works for ZODB profiling.
