The without-interrupts ensures that we don't write partial sexps to
the Emacs buffer.  If Lisp receives a SIGINT before the expression is
completely written, we enter the debugger and send some debugger
messages to the stream, but Emacs will not be able to parse it
correctly.

This occurs very likely if you remove without-interrupts*, set
*use-dedicated-output-stream* to nil and run the
interrupt-bubbling-idiot test case.
