-Re: Prewarming in-memory column families

It's touchy... what if the data set doesn't fit in the in-memory's
part of the block cache (which is 25%)? Maybe the user only wants to
keep "in-memory" those edits that are being used? What about the IO
hit of assigning those regions at startup that would now need to read
X GBs all at once?
FWIW I've never been a fan of that setting.
