The problem is that it's impossible to have a 100% portable interpreter,
because of  internal calls and P/Invoke.  Both of these invoke native
code, either within the runtime itself or within a shared library, and
this requires processor-specific code to place parameters in the correct
registers, etc.

Since processor-specific code is required *anyway*, it was considered
reasonable to just require the JIT for most uses, since (afaik) the JIT
doesn't require _much_ more custom code than the marshaling code already
