DESCRIPTION

       This function returns a number 0..N, which is the unique index of this particular script
       execution from a swarm of “stap --remote A --remote B ...”  runs, and is the same number
       “stap --remote-prefix” would print. The function returns -1 if the script was not launched
       with “stap --remote”, or if the remote staprun/stapsh are older than version 1.7.
