Comment (by dmsnell):

 Given that there was no further feedback I felt it would be best to get
 this merged sooner rather than later to give folks ample time to discover
 any issues with it in `trunk`.

 Thanks for your work on this @kraftner and @ramon-fincken!

 @peterwilsoncc (or anyone) - given that this originated in 5.5, what is
 the policy for backporting fixes? is it old enough that we simply move
 forward, or should we attempt to apply this fix to the old branches?
