Yes, you can do that in the upcoming 1.1.8 (current 1.1.x from svn).
You can use the built-in queue provided by Fl::awake/Fl::set_awake_cb,
which provides "several thousands unreliable messages" to be queued.
If you need greater control, you can implement your own by using a
custom queue and awake() solely to interrupt Fl::run().
There's a new chapter in the documentation ("Advanced FLTK") which
discuss those functions in more detail.
