Hi,
Start Emacs with the -Q option.

Then I get unable to break it. So is Emacs 24.3. This may happen
only on Cygwin, though. It makes me hard to debug a code suspected
to have an infinite loop.
I can confirm that this happens on Cygwin but not on GNU/Linux. This may
just reflect the fact that Cygwin doesn't have SIGIO. Maybe someone who
understands how Emacs handles keyboard input can weigh in on this and
suggest a workaround.
FWIW, I am able to successfully interrupt that loop via C-g on my
Cygwin system, which was configured with the --with-w32 flag and built
from yesterday's trunk.
