-/**
- * This function is called once a second from the mainloop.
- * It is intended to do background checking on all the user structs, e.g.
- * stuff like ping checks, registration timeouts, etc.
- * The function returns false when it is finished, and true if
- * it needs to be run again (e.g. it has processed one of a batch of
- * QUIT messages, but couldnt continue iterating because the iterator
- * became invalid). This function is also responsible for checking
- * if InspSocket derived classes are timed out.
