I use it for the automatic unlocking macros for example. Or to close a 
stream/fd, or to do manual profiling of hot spots - you just have one 
ifdef block at the top, and not littered all over the function at all 
return points, or if you're building some kind of message that you must 
always write() to a pipe before returning, etc.
