 I want to setup a build bot for generating Haskell binaries in an
 automated fashion, however even with 4 GB of RAM, cabal is unable to build
 HLint in HardenedBSD. Specifically, GHC is choking on mmap errors while
 compiling HLint's huge dependency tree.

 Can we somehow shrink the massive memory usage of GHC, so that common
 packages HLint can be built on medium-low build bots? Imagine GHC running
 on a RaspberryPi: You're gonna have a bad time.
