Previously, if instance() was accessed concurrently we could run into various problems as the initialization wasn't synchronized. By putting most of the initialization into the constructor, wrapping it into a Q_GLOBAL_STATIC and discerning between accesses that need to wait for the initial "hello" packet and ones that don't the situation is improved.
