The getStackframe[ function is the primary
(low-level) window into the loop stack. It returns a keyval
block describing the given stackframe (n must be a
non-negative integer less than job
countStackframes).
If @$s.actingUser doesn't "control" the stackframe
in question, the getStackframe[ return block
contains only
[ :owner o |
where o is the "owner" of the stackframe;
otherwise it returns a full dump of the contents of the
stackframe. For a precise description of this dump,
see section `Loop Stacks' in Loop Stacks.
The "owner" of a stackframe is the value of
@$s.actingUser at the time the stackframe
was created. A job "controls" a stackframe iff
@$s.actingUser for the job is the owner
of the stackframe, or else is root running with
the OMNIPOTENT bit set.
