What does the "no platform punt-keepalive disable-kernel-core" command mean?

I'm just trying to get some clarification on what the command "no platform punt-keepalive disable-kernel-core" means? I have a brand new 4331 router and "no platform punt-keepalive disable-kernel-core" is part of the out-of-the-box configuration. This best explanation I could find online was: 

"To enable the Punt-Keepalive feature and monitor the status of the punt path between the forwarding processor (FP) and the route processor (RP), use the platform punt-keepalive command in the global configuration mode. To disable the Punt-Keepalive feature, use the no form of this command."

I'm a little foggy on what the "punt path" is but I believe it has to do with packets being sent down to the next processing level. I don't quite understand how this works or what components are involved.

What I want to know is should I leave the "no platform punt-keepalive disable-kernel-core" configuration as is, or should I enable it? What are the pros and cons of leaving disabled/enabled?

Kernel core with which we can troubleshoot further.

just leave it as it is :)
