>>> from pcbnew import *
>>> brd = LoadBoard('test_dr.kicad_pcb')
>>> drs = brd.GetDesignSettings()
>>> drs.m_HoleToHoleMin
37845792 <== I don't know where this value comes from.
>>> drs.SetMinHoleSeparation(12345678)
>>> drs.m_HoleToHoleMin
12345678 <== New hole-to-hole setting.
>>> brd.SetDesignSettings(drs)
>>> brd.Save('test_dr.kicad_pcb') <== Save updated board.
>>> brd = LoadBoard('test_dr.kicad_pcb') <== Reload updated board.
>>> drs = brd.GetDesignSettings()
>>> drs.m_HoleToHoleMin
0 <== Updated hole-to-hole setting has been lost.

This same problem affects m_RequireCourtyards and m_ProhibitOverlappingCourtyards.
The only commonality I can see is that none of these member variables have the drs.Get*()
methods (e.g. drs.GetMinHoleSeparation()).
