Is there any way to call Marshall in a type-safe way?  I need to use 
marshaling for a networking program, and I'd rather not leave Marshal 
as an arbitrary code execution vulnerability (which it is as far as I 
can tell: switching on a Marshaled value should produce a computed 
jump, which can be set by an attacker to point to an arbitrary place).  
Am I stuck writing my own marshal function?
