This will indeed read a 32-bit integer, but on a 32-bit architecture
ocaml int's are 31-bit, so you loose the highest bit.
Note that on a 64-bit architecture this is sufficient for 32-bit
integers!

This one reads a string...
> val Marshal.from_channel : in_channel -> 'a
And this one reads a marshalled value, which must include a special
header indicating its ocaml representation.
So if you really need to read a full 32-bit integer, none of these
will work, and you must do the job by hand.
