Comment (by sgraf):

 If I force `data_areas` in `synth_2` like this:

 {{{
 foldr seq () data_areas `seq` synthd_assy ++ data_areas
 }}}

 the non-determinism is irreproducible. If I instead force the whole list,
 like this:

 {{{
 let res = synthd_assy ++ data_areas
 in foldr seq () res `seq` res
 }}}

 it's non-deterministic still. Seems like this isn't really possible to
 localise?! I'll leave this for another day.
