are you telling me that a policy with only a single rule
"any any any accept"
  will eat up all the CPU cycle on a dell machine with P4
2.8 Ghz processor
  and 2GB ram during a policy push?

You have the flapping effect during policy install because a
policy
install starves the CPU for too long a time. We all know
that a policy
install eats up all CPU cycles for a while on any module.

So there you see the flapping during the policy install.
