Re: Supporting POSIX *users*

   A single bug in a single application allows the attacker access to
   the whole system.

Not at all true.  Maybe you if refer to suid root programs, yes, but
the worst case is that you only get access to someones home directory
which is not anything near `access to the whole system'.

PS. Please fix your mail client not to send base-64 encoded messages,
a proper mail client will send them in a mime attachment without
resorting to encoding it using base-64.
