Not sure whether it'll work any better, but there is run-with-idle-timer.
C-h f run-with-idle-timer <RET> says:

,----
| run-with-idle-timer is an interactive compiled Lisp function in
| `timer.el'.
| 
| (run-with-idle-timer SECS REPEAT FUNCTION &rest ARGS)
| 
| Perform an action the next time Emacs is idle for SECS seconds.
| The action is to call FUNCTION with arguments ARGS.
| SECS may be an integer, a floating point number, or the internal
| time format (HIGH LOW USECS) returned by, e.g., `current-idle-time'.
| If Emacs is currently idle, and has been idle for N seconds (N < SECS),
| then it will call FUNCTION in SECS - N seconds from now.
| 
| If REPEAT is non-nil, do the action each time Emacs has been idle for
| exactly SECS seconds (that is, only once for each time Emacs becomes idle).
| 
| This function returns a timer object which you can use in `cancel-timer'.
