Fast or safe, pick one. CVS has no integrity check and you will never know
if you have bad data or not. And the BK checks find el cheapo memory dimms
and all sorts of other problems all the time. It even found a cache aliasing
bug in SPARC/Linux...
The BK integrity check will tell you right away if any of your data is bad.
*Everyone* hates the check until it saves their butt and then they decide
it's not such a bad idea. It's a lot like a seatbelt - you don't like it
until something goes wrong.
BK != CVS. You want fast and loose, by all means, use CVS, that's not our
intended market and we don't care about fast where fast means bad data.

Mount the file system with noatime.
Buy enough memory to fit the kernel in memory and on a 1Ghz processor that
pull will take about 20 seconds. Even laptop memory is pretty cheap these
days. Pricewatch says $80 for .5GB for laptops, that's cheap.
