Miracle patch out-performed by four lines of bash

Well it’s nothing if not interesting. The ~200 line “miracle” patch promises a huge improvement in desktop responsiveness, but Lennart Poettering (from Red Hat) has replied to Linus’ praising comments with 4 lines of bash which out-perform it, on the current vanilla kernel. (And by the way, Lennart seems to agree with Con Kolivas about this patch, in that make -j is not a valid desktop use case.)
