happens only once.  Perhaps once a day, week, month, and even year.

But the Apache case is to start with 5 processes, start 145 new
processes in a few seconds and then kill 140 again after maybe
30-45 seconds. And repeat.

 
Perhaps the real problem is using a poorly designed application,
regardless of how popular it might be?

I don't see any evidence that leads me to believe that was
actually a problem.  I do see evidence that you assumed there
was a problem where, in fact, one did not exist, and that you
failed to investigate sufficiently before jumping to
conclusions.
