 Building package https://hackage.haskell.org/package/unicode-properties
 uses extraordinary amounts of memory with recent compilers - it dies on my
 16GB desktop, though the travis build does eventually complete (see it
 here: https://travis-ci.org/seereason/unicode-properties/builds/65815442.)
 I have imported the repo to github and untabified it here:
 https://github.com/seereason/unicode-properties.  Building this package
 was somewhat slow but did complete under ghc-7.8.3.
