this code is wrong. if your actual code looks like this, it will never
do anything. i would hope that your code looks more like:

   pthread_mutex_lock();
   while (!some_condition_variable_set_in_your_code)
      pthread_cond_wait();
   pthread_mutex_unlock()

i have written many multithreaded apps with GTK+, gtkmm and pthreads
(linuxthreads) and i can assure you that they work together just fine.
