Hmm.. the patch below tests whether some input is available after
sending something to Emacs.  If so the input is processed immediately.
So, typing `C-c : (break) RET' should give you a debugger the next
time something is sent to Emacs.  You also need to add

  (setq swank:*use-dedicated-output-stream* nil)

to your ~/.swank.lisp.  (Otherwise output is send to an extra stream
for efficiency reasons.)

Not that I know of.
