Responsible-Changed-Why: 

I'll give this one a try.  The submitted patch looks like it solves
what might be a file library routine buffering issue/file locking
issue but pw(8) might need more work than just that.  I looked it over
a bit and can't see where it is using normal password file locking
to avoid problems with vipw(8) running at the same time, etc.
