It works exactly the same as rm -f for the system immutable bit.. ie: both
fail.

However, rm -f will turn off the user immutable bit if run by root.
Perhaps I should recover the code, but only let it turn off the *USER*
immutable bit, just like rm -f does?
At least that'll stop users creating user-immutable files in /tmp to annoy
the sysadmin...
