/**
 * WvTimeoutStream is a stream that becomes !isok() after a
 * configurable number of milliseconds. It will wake up a select(). It
 * will return true if select()ed and that the timeout has
 * expired. But using it in a WvStreamList will not have it call the
 * callback/execute because the WvStreamList checks whether isok() is
 * true before doing the select().
