  Maybe I wasn't clear enough :-)

  Let's say I have a function runed with `run-with-idle-timer'. This
  function has an infinite loop somewhere in it.

  Now,  this  function  is  called,  asynchronously.  The  call  being
  asynchronous, I don't  know how I can stop this  function and have a
  backtrace, in order to know where the infinite loop is.

  I mean... with (run-with-idle-timer 1 nil (lambda () (while t))),
  how do you unblock emacs ?

  Thanks.
