proctop.stp:  Periodically print process info while keeping a history

Description:
  Every 5 seconds, print out a list of 25 processes that took the most
  system time with information about the processes. Includes information
  on processes that may have exited while the script was running. The
  script contains configuration options listed in the script source.

This is the default configuration of the proctop.stp script. It sorts based
on cpu time, and only shows a max of 25 processes.

A configuration that might be useful would be to sort by the state to see a
short list of the processes that have stopped while the script was running.

$ stap proctop.stp -T 12 -G show=5 -G sort=state -G sortby=decrease
