Review Comment:
In a procedure's whole life time, it could reach here multiple times. For
example, if it schedules some sub procedures, it will suspend itself for a
while until all the sub procedures are finished, it will recover the execution.
So I think if we want to trace procedure execution, we need to discuss more,
and better to have a design doc first. It is not very straight forward, as how
to define the relationship between parent procedure and sub procedure?
