Newbie question on checkpointing resource

[Khanduja, Vaibhav]

@

I apologies for flooding mail boxes but was wondering if I could get more info 
on “CheckPoint Resource”.  I see slave code and find following code:

"

void Slave::checkpointResources(const vector<Resource>& _checkpointedResources)

"
Does CheckPoint resource mean the state of the resource can be 
preserved/CheckPointed?  I got reached to this code while understanding 
persistent volume implementation in 0.24.

Thanks
