Just to check on what the requirement is, if there was an emulator under 
which your code would work successfully would you still want your code to 
exit or would you want it to go ahead and execute?

Yes. In principle, the better the emulation the harder it will be to detect. 
As you acknowledge, detecting whether the program is running under an 
emulator is like chasing the wind. Each time a better version of an emulator 
comes it it may become harder to detect. Hence my query about the 
requirement.
