There's a linuxolator bug in the kernel that the latest SAs unhid.

This appears to break all X-using Linux code -- both applications and plugins such as the widely-used flash plugin -- and probably other Linux applications too. I am working on a fix for this and will send an updated advisory out as soon as it's ready. -- Colin Percival Security Officer, FreeBSD | freebsd.org | The power to serve Founder / author, Tarsnap | tarsnap.com | Online backups for the truly paranoid It seems to me that work is surely in progress before I sent send-pr. I don't want to confuse The FreeBSD Project developers.
