it can't. the osd is a static object. there is only one at any time.
when there is already an osd open cOsd::OpenRaw(x, y) will return NULL.

cOsdBase *cOsd::OpenRaw(int x, int y)
{
  return osd ? NULL : cDevice::PrimaryDevice()->NewOsd(x, y);
}

the osd gets closed just before the main thread ends. so there is
nothing to wait for.
