I have a really hard time following this.  Are you seriously saying
that GHC is inlining code from modules _and_ link dynamically at the
same time.  That seems like a remarkably strange thing to do, or maybe
I'm just missing something.

My understanding from another thread on here was that dynamic linking
isn't working reliably, not even on Windows, where it once was
supported.  It has never worked on any other platform.  Am I wrong
about this?  IIRC I've never seen GHC produce anything that's
dynamically linked to _any_haskell module, and all modules I compile
are always packaged up in .hi and .a files.  Not a .so or .dll as far
I can see.
