Right. But with the current two candidates (LRU and ARC) in the field
only, there isn't much to compare. If someone wants to implement another
algorithm, I will be happy to put the required switchboard (something
like the jump table in smgr) into the code. Right now I see much more
bang for the buck in creating the background writer.
