But I bet Drew's code works just fine, when it does not crash.
Anyway, if switching away of the frame inside save-window-excursion is
not allowed, we should detect that and signal an error. That would
solve this bug cleanly, with no need for any low-level hacking or
kludges.

But if you say that switching a frame inside save-window-excursion is
not supported, why do we need to change code to support it? What am I
missing?
