There is no parallel processing when loading the image. It is all ready as
soon as your image loading function returns. There will be a delay if you do
not call Fl::flush(), Fl::wait() or Fl::run() though.
I suggest that you write a short example program which has the problem that
you describe, post it here, and we will see where the problem lies.
