I was hoping someone might comment further on the selinux issues, I woudl gather from this though that the native implementation must now avoid the "selinux doesn't like pages that are both executable and writable" issue? http://hackage.haskell.org/trac/ghc/ticket/738 (it seems like the solution that closed 738 was to use libffi) Cheers! -Tyson
