[-- Attachment #1 --] FYI, I accidentally ran a post-statfs alpha world inside a chroot on the August-ish 5.1-C alpha machines, and it caused half of them to lock up (no break to debugger possible from serial console, no console messages - including the signal 12s that I'd expect to be there from the binaries running inside the chroot). It looks like they locked up with the first incompatible binary they ran, instead of dying with signal 12 - or perhaps they ran a binary that did not use the new syscall, but did something else to cause the lockup. The machines that didn't lock up have lots of sig12s on the console, but they also became unresponsive for an hour or so while this was going on (my heartbeat monitoring script could not connect to any of the cluster machines, although half of them eventually started allowing ssh connections again).
