  Were situations like those in this thread (i.e. a new or newly exposed
  window that happens to be under the pointer) handled correctly in twm?

In my case, yes. I spent some time staring at the twm code and comparing it
to openbox but never did get it figured out.

Another thing that twm got right but doesn't work in openbox is taking focus
away from a window when the mouse leaves it.

Considering that 'focus-follows-mouse' is how God's window manager works,
it's very hard to find an earthly window manager that gets it right.
