Cannot overload functions after all previous overloads have been evaluated

[GoogleCodeExporter]

What steps will reproduce the problem?
Stub a function on a mock_object N times with overloaded return values. Call 
the function on the mock_object's instance (getInstance()) N times. Stub the 
function again with another overload. Call the function on the instance and 
observe that the last overload did not take effect; the returned value is that 
which was specified in the Nth overload.

However, if you stub the function with N overloads, then call the function 
(N-1) times, then add the (N+1)th overload, then call the function twice more 
you observe that the (N+1)th function call returns the value specified in the 
(N+1)th overload, which is exactly what you would expect. (Any subsequent call 
also returns this same value, as expected.)

See attached code.

What is the expected output? What do you see instead?
I expect that no matter the state of the mock_object and how many times the 
instance functions have been evaluated, setting a new stub overload will cause 
that overload to take effect as early as possible; in particular, if there are 
other non-evaluated overloads the new overload will be queued at the end, and 
if all overloads have been evaluated the new overload will take effect on the 
next function call.
