I've confirmed this is a UFS bug related to sparse files: "truncate -s20G f1 
&& rm f1" is enough to trigger the error and start generating .viminfo files 
that appear to be 20GB. When running fsck I get an "Invalid block count" error 
if I just reboot without removing the .viminfo file; if I do remove it, I get 
a "Partially allocated inode" error.
