Usage: (NOT a cligen utility)
pid2 [integer(300)]
The [] notation here indicates optionality and default is in ().
This program just does vfork() as fast as possible to wrap a Linux process
table until the target Process ID integer is reached.
PID-wrapping was made famous more as a hacking tool for programs which foolishly assume the next PID is neither predictable nor re-used (e.g. a shell /tmp/foo.$$ construct).
I am publishing it here mostly as an example of a big effect that OS scheduling affinity for a particular CPU can make. It can also sometimes be nice to "position" within the process table if you often do PID-sorted process table listings..(e.g. to group all your xterms or shells together).
