GHCi doesn't use the threaded runtime though.  So given that:

    "To allow foreign calls to be made without blocking all the Haskell
    threads (with GHC), it is only necessary to use the -threaded option
    when linking your program, and to make sure the foreign import is
    not marked unsafe. "

So I think this is expected?
