You don't find races and bugs on emulators the same way as on real hardware. Also, if you do find a bug in your emulated environment, how much time would you spend wondering if the emulator is bad or your code? Also, there is a real chance that the emulator would let stuff pass (like allowing code make memory or bus access on odd address or some other restraint) which really shouldn't be allowed and you would not notice it.
