I guess it would be possible. If you happen to abort exactly after the
connection is made but before the request is sent. Surely that time span is
*very* brief in real life and the number of connections you cancel in that
state should be very few? In other words: I doubt it is worth all the added
code and logic for such a very slim chance.
