Dude... 7-CURRENT has several improvements to MP systems, but it's not meant to be the 'first non-SP designed OS'. Please, get your facts straight.. There are several other improvements coming with 7-CURRENT though, mainly dealing with Mac support, some security auditing (I believe), and other SoC / important developer project work, as well as improved hardware support for some items like SATA and HD audio I believe. And yes, there's the big [ULE] scheduler / giant lock removal improvement which helps MP systems scale better with 7-CURRENT. But that doesn't mean that the 4BSD scheduler doesn't do MP systems well. It just sucks at it compared to ULE =P. -Garrett
