Ok, I see the problem...

Would it be ok to put something like
  static int inited;

  if (inited == 0) {
    return;
  }
  inited = 1;

in sws_global_init()?
(of course, sws_global_init() should not be called in a multithreaded
environment without protecting the call with a mutex)

Or do you prefer some other kind of solution?

			Thanks,
