Brett Cannon's sandboxing work (which aims to provide first-class support for 
multiple interpreters in the same process for security reasons) also seems 
like a potentially fruitful approach to distributing processing to multiple cores:
   - use threads to perform blocking I/O in parallel
   - use multiple interpreters to perform Python execution in parallel
