The class RExec exports methods r_exec(), r_eval(), r_execfile(), and
r_import(), which correspond roughly to the built-in operations
exec, eval(), execfile() and import, but executing the code in an
environment that only exposes those built-in operations that are
deemed safe.  To this end, a modest collection of 'fake' modules is
created which mimics the standard modules by the same names.  It is a
policy decision which built-in modules and operations are made
available; this module provides a reasonable default, but derived
classes can change the policies e.g. by overriding or extending class
variables like ok_builtin_modules or methods like make_sys().

XXX To do:
- r_open should allow writing tmp dir
- r_exec etc. with explicit globals/locals? (Use rexec("exec ... in ...")?)

    Code executed in this restricted environment will only have access to
    modules and functions that are deemed safe; you can subclass RExec to
    add or remove capabilities as desired.

    The RExec class can prevent code from performing unsafe operations like
    reading or writing disk files, or using TCP/IP sockets.  However, it does
    not protect against code using extremely large amounts of memory or
    processor time.

        The hooks parameter is an instance of the RHooks class or a subclass
        of it.  If it is omitted or None, the default RHooks class is
        instantiated.

        Whenever the RExec module searches for a module (even a built-in one)
        or reads a module's code, it doesn't actually go out to the file
        system itself.  Rather, it calls methods of an RHooks instance that
        was passed to or created by its constructor.  (Actually, the RExec
        object doesn't make these calls --- they are made by a module loader
        object that's part of the RExec object.  This allows another level of
        flexibility, which can be useful when changing the mechanics of
        import within the restricted environment.)

        By providing an alternate RHooks object, we can control the file
        system accesses made to import a module, without changing the
        actual algorithm that controls the order in which those accesses are
        made.  For instance, we could substitute an RHooks object that
        passes all filesystem requests to a file server elsewhere, via some
        RPC mechanism such as ILU.  Grail's applet loader uses this to support
        importing applets from a URL for a directory.

        If the verbose parameter is true, additional debugging output may be
        sent to standard output.
