There must be some saner way to solve that problem. For integer
arguments, the network stubs could integers in some bignumish way, and
the receiving stub would convert it to the local machine word or
return an int-is-too-big-error message on overflow. (To get it right
one must treat signed and unsigned integers differently, of course).

It might get a little more complicated with struct arguments, but
there the stubs already have to do endianness conversion and perhaps
also some alignedness fixups.

If it's too late to fix Mach, I hope we can at least do better for L4.
