In the civilian aviation world, the runway should be used by one airplane at a time.  No "section" (formation) takeoffs, no landings five seconds apart, no "taxiing into position and hold".    Do not sit on a runway waiting for the previous airplane to taxi off.  "Position and hold" is a tower controller command and this maneuver should not be used by pilots at non-towered fields.

     If you need to make a precautionary landing, while in the pattern at a non-towered field, and the distance between your aircraft and the one ahead of you is closing, make a call advising the traffic of your problem and asking him to go around so you can land on an open runway and avoid any conflict.  You have the emergency and other airplanes will only know that when you declare the emergency and stake your claim for the runway.
