Victor,

   I am no expert in the shutdown logic that Arch uses, but it is fairly easy 
to follow. During shutdown, /etc/rc.shutdown is called and the 'umount_all' 
command is supposed to take care of unmounting all non-api filesystems. If you 
have specific commands you need run in _addition to_ what is done by 
rc.shutdown, then you can put those commands in /etc/rc.local.shutdown. The 
/etc/rc.local.shutdown must be executable to be called (chmod +x) or (chmod 
0755). The rc.local.shutdown file is called close to the beginning of rc.shutdown.

   Looking at your mtab file and comparing to mine, I do not have any usb 
drives connected to my system. Somebody more familiar with issues related to 
usb drives will need to comment. You might want to try Guillermo's shutdown 
modified as follows:

umount -arfl -t usbfs,fuseblk

   I don't know if that will do it, but you have 5 fuseblk filesystems and 1 
usbfs mounted. I don't know how Arch handles their unmounting.

   Lastly, I do not use the gnome gvfs-fuse-daemon. That is another entry to 
look at and make sure it isn't the issue. Maybe try your rc.local.shutdown with:

umount -arfl -t usbfs,fuseblk
killall gvfs-fuse-daemon  # or whatever that process actually runs as
