Haven't checked your patch yet (still in the office).
But I had an idea on how to deal with this without using
locks/counters/whatever:

How about using a separate class for the screen/view vector. Access to
the vector is controlled by the class methods. That way, you can just
set a flag "rebuild necessary", and the vector is then rebuilt on the
first read access.
With such an implementation, the vector really is only rebuilt when necessary.

Thoughts?
