OK.

An input char goes into unread-command-event. Since nobody handles it,
the while-loop runs forever.

The char event shall be taken from unread-command-event, and (for
example) inserted into the current buffer.

Then we have the initial situation, as reported by Peter. The char is
put into the let-bound unread-command-events, and it is lost when the
let-clause ends.

I simply don't know, who shall be responsible to move an event from
unread-command-events. In the example I've shown above, it is not done.
