Hi,
Optionally disabling executable heap blocks would be a separate patch.
As far as I know, the only reason that the heap is executable is to
support the adjustor thunks used to implement "wrapper" imports. The
"static_wrapper" patch provides a way to install Haskell callbacks in
many C libraries without the need for adjustor thunks.

I thought of implementing the feature as a preprocessor but it did not seem very easy to do because we need to parse Haskell types.
Something doesn't add up for me here. If *all* GHC-compiled programs require an executable data segment, then how could a preprocessor possibly remedy this problem? (and likewise, how does the static_wrapper patch do so...)
