If this is true, maybe it is a redisplay bug. Could you try interrupting Emacs through gdb when this occurs, and inspecting Vtimer_list to see if the `blink-cursor-timer-function' timer is still active? Another avenue of investigation is to add (redisplay) to `blink-cursor-timer-function'. If that stops the problem, that means there is a redisplay bug. I have unfortunately been unable to reproduce this bug.
