It would be really cool if redis supported the ability to count the high bits in a string as a native command. No need to pull a 16k string down to client

Although it is another command in a growing list of them. maybe something for lua.

This is something that should probably be implemented natively, for speed. Preferably with GCC's __builtin_popcount intrinsic, if it's available.
