What I have observed is that when you "su" to root, your history file gets
remade and is now owned by root.  Now when you exit "su" back to your original
login, ksh can still continue to use the history file (probably 'cause it's
already opened) but when it comes time to remove it when you exit ksh, you
can't because it is owned by root.
