A little of topic, but I remember reading once from facebook that when a web user give focus
to the inbox search box they sent a message back to warm the appropriate caches. I think it
may have been in the original paper.

Out of interest is there a way to warm the key cache, other than say sending a get_range_slices
command that asks for 0 columns?

I don't have a particular need to do this, just wondering.
