X indeed freezes: no window updates, no response to mouse events (except that the cursor moves), no response to keyboard events (Caps Lock doesn't work, either). I got the backtrace by following the instructions at https://wiki.ubuntu.com/X/Backtracing, i.e., logged in remotely, ran gdb and attached to the Xorg process (which was consuming >100% CPU). Btw forgot to attach .xsession-errors, doing that now. Since reporting the bug, I've had this happen twice more. Both times, gdb showed Xorg to be stuck in exactly the same place. Attaching those (virtually identical) backtraces.
