This doesn't happen when I run make directly from a shell myself. It looks like a defect in the GHC builder-client itself.
I would rather call it (yet) an undocumented feature :-)
If POSIX resources are available on the host (which they are on SmartOS) builder-client sets a 1GB ResourceTotalMemory limit using System.Posix.Resource.setResourceLimit: https://github.com/haskell/ghc-builder/blob/master/client/client.hs#L54
Yes, I think your diagnosis is right. The builder-client sets that memory limit for each launched process so it could avoid uncontrolled consumption. But the original 1-GB limit may be too strict these days, as the build phase could easily exceed this (legally), especially on 64-bit architectures. Probably this should be factored out to a configuration file or increased to 2 or 4 GB.
