Batteries getting removed with no AC should not be a very frequent  
occurrence, one would think. Yes, it'll happen, but treating it as the  
case to optimize for seems ill-advised.

This is irrelevant. The page cache is just a cache -- it shrinks in  
response to actual memory pressure. If applications gobble up all the  
RAM, the page cache is small enough as to make the FS effectively  
become synchronous. Applications don't suffer by having less RAM to go  
around.
