I thought the next step was rather obvious. If there are certain opcodes that can take a long time to run, then the code run by those opcodes should be made smarter, releasing the critical section (or whatever else it might be called) during the parts of the opcode when blocking I/O is being done and unlocking it briefly and repeatedly at 'safe' points if the opcode involves some long-running actions such as looping.
