4 * Various SNAC-related dodads...
6 * outstanding_snacs is a list of aim_snac_t structs. A SNAC should be added
7 * whenever a new SNAC is sent and it should remain in the list until the
8 * response for it has been receieved.
10 * First edition badly written by Adam Fritzler (afritz@delphid.ml.org)
11 * Current edition nicely rewritten (it even works) by n (n@ml.org)

74 * a reply was never received for. Garabage collection. Plain and simple.
76 * maxage is the _minimum_ age in seconds to keep SNACs (though I don't know
77 * why its called _max_age).
