Thanks, I see it now, at least in the MS-DOS version.  Curiously, in
a Unix tty Emacs doesn't hang.

I suspect that's because C-g doesn't produce a signal on Windows.  I
can get the MS-DOS version out of the infloop with C-BREAK, which in
that version of Emacs does produce a signal that interrupts any code
(except for very tight loops and system calls).
