After some further reflection on this point, I don't think it will be  
necessary to make llvm_start_multithreaded() strictly required for all  
applications that want to host threaded applications in the JIT.  It  
is, however, strongly recommended, especially if you're using side  
exits, to guard against to possibility of accidental concurrent calls  
into the LLVM API.

I still welcome any comments, particular from VM implementers.
