Hash :7289d7f8 Message :Fix a potentially very annoying evdns bug that we found in Tor.
Generally speaking, it way better to event_assign() an event when you
allocate it than to assign it before every time you event_add it: if
it is already event_add()ed, the assign will mess it up so that it
doesn't _look_ added, and event_add() will insert a second copy.
Later, event_del() will only delete the second copy. Eventually, the
event_base will have a dangling pointer to freed memory. Ouch!
