[Agda] Warning: hashable-1.2.0.x has serious performance bugs

When you compile Agda, make sure it uses hashable-1.1.2.x and not the
newer 1.2.0.x version (which cabal automatically pulls if the choice is
not constrained).
With hashable-1.2.0.x, Agda is 10x slower!
The newest darcs version asks for hashable < 1.2, so
cabal install
might not work out of the box, you might have to clean out newer
versions of hashable and reinstall packages that used hashable-1.2.0.x,
like the hashtables package.
cabal configure -v
should show you which version of the packages are picked for compilation.
Cheers,
Andreas
