The bug is in the following loop of `flyspell-word-search-backward'

       (while (and (not r) (setq p (search-backward word bound t)))
	(let ((lw (flyspell-get-word '())))
	  (if (and (consp lw) (string-equal (car lw) word))
	      (setq r p)
	    (goto-char p))))

which, IIUC, is run by a `post-command-hook' and thus does not permit
quitting.  On the other hand, the intangibility property doesn't permit
to move to the desired position and thus the loop is never exited.  The
patch I sent earlier should correct this (although, I think, that loop
_is_ asking for troubles).

As an aside: This is the first time I try flyspell and I noticed that
it's unbearably slow.  Shouldn't the checking stuff be run by a timer?
