This function is supposed to be called when we are short on cache space (and other things) and need to reclaim space. However ... it isn't implemented anywhere. This codepath changed with commit d29643b0553011cbe60dd127fd31c1847fe02ddb, which enabled disconnected mode always for unix clients -- the old version (for non-disconnected mode) used a different function. It will probably be a while before we rewrite things properly (as it is not exactly clear what "properly" means, at least to me). -Ben
