* Hold for >20s after GPS lock
GPS chips are designed to stay locked for a while to download some data and save it.
This data is important for speeding up future locks, and making them higher quality.
Our present configuration could make every lock perform similar to first lock.
This patch sets a hold of between 20s and 10% of the lock search time after lock
is acquired. This should allow the GPS to finish its work before we turn it off.
