Turns out I messed up with one of Neil's review comments. Here is yet another 
update.

With this fix, everything works as expected in testing now. sys_getcwd 
returns -ENOENT for paths not connected to the chroot. /proc/mounts 
and /proc/$pid/mountstats never contain a relative path. gnome-vfs-daemon 
seems quite happy again.
