Can't remember.. The only thing I can come up with is that 20 was the
next round number that is larger than IEEE80211_SCAN_INTERVAL_SLOW
defined on the previous line.. ;-) Anyway, I don't see why we would need
to wait that long. It should be enough to wait for a full scan of all
channels to be completed. It is of course nicer to avoid creating a new
IBSS if there is an existing one, but as long as merging works, it
should be fine to reduce this timeout.
