see  http://www.gtk.org/faq/#AEN602

Basically, just put a 

    while (g_main_context_iteration(NULL, FALSE));

inside your for loop somwhere, possibly surrounded by something like an  

  if ((i & 0xff) == 0)
  {
     while ...
  }

to make sure g_main_context_iteration() is not called with every single 
iteration, but only after 256 iterations or so (depends on your specific 
context of course).
