All these reservations surely need to go into your entry in the PROBLEMS
file.  People run Emacs as root, e.g. for editing configuration files.
Do we really expect users to be able to flip setuid bits, or remove
SYS_TTY_CONFIG capability?  Myself, I don't even know what the second of
these means, though I will examine the thread to try and find out.
