How about making an "AS_ROOT" macro which you could use like this:

  AS_ROOT {
    stuff ();
  }

I am envisioning something like this:

  #define AS_ROOT  for (int _i = 1 ; become_root(_i) ; _i = 0)

(Where become_root() takes an argument for whether to "become" or
"unbecome", and it returns its argument.)

The only problem with this macro is that it uses a C++-ism.  If you
need straight C, you could define two macros which you would use like
this:

  BECOME_ROOT
  stuff();
  UNBECOME_ROOT


  #define BECOME_ROOT  { become_root();
  #define UNBECOME_ROOT  unbecome_root(); }

This is no easier to use than the current scheme, but it will give a
compile-time error (unbalanced curlies) if you screw up.

Just a thought.
