Code insertion

Hi all,
Just wondering if someone could help me with this rather specific problem.
I am trying to figure out where i should insert some code that basically
resets stats after a certain number of transactions(or sql statements)
have been executed. Collects Stats after some more statements have been
executed and continues to do this.
I need to access these stats so i store them in Shared memory.
The long term goal is to reset stats, collect stats, reset stats, collect
second set of stats, compare 1st and second stats. Therefore i can't have
the 1st or second stats rewritting itself.
I had this problem when i tried to insert the code in the Executor under
ExecutorRun().
