I believe marshaling of functions did not always work nicely with
dynlinked code. More fundamentally, we cannot rely on the generic
marshaling of data, for the reason I mentioned (some data types require
special handling), and it's very difficult to know exactly what is
captured by a closure. In practice, the computation functions capture
some values such as global values (global memoization hashtables, etc),
and it would be wrong to marshal them.
