Besides those changes, I you'd also need to change `-F0` argument for 
lsof to just `-F`.  This would have problems if there are filenames 
which contain newlines, but I suspect that wouldn't happen.

Even with the above it just echoes the touch command rather than 
actually running it, so the `echo` needs to be removed as well.  This 
wouldn't be noticed if the lsof command isn't modified, since sed will 
fail to match anything leaving nothing for xargs to do.

A better option may be just backing out the change that introduced this, 
it definitely doesn't look like it was tested enough to have been 
introduced in a security update.
