Something like that, yes. Currently you can get silent errors when
Marshal fails to set the stream to binary. Without knowing about this
internal feature in Marshal, it is very hard to find these errors.
In the case of our Madeleine library, it worked in three our of four
cases, making the single broken case quite confusing.
Alternatively the code in Marshal that sets the stream to binary could
be removed entirely, which would also make it more "fail-fast".
