One example is that the utility that plots the data needs to leave blank 
the time of sleep. Without inserted records for stopping and starting the 
accounting process, it would have to incorporate some logic, like "this 
time difference looks too big, don't plot in-between".

It's doable, but it makes sense to be solved at a different level.
