/*	Passing in a level value which is outside the range of 0-7 will cause the the call to do nothing.
	CFLog() logs the message using the asl.h API, and uses the level parameter as the log level.
	Note that the asl subsystem ignores some log levels by default.
	CFLog() is not fast, and is not going to be guaranteed to be fast.
	Even "no-op" CFLogs are not necessarily fast.
	If you care about performance, you shouldn't be logging.
