Admittedly, it may not occur in the particular situation you're looking at, but can you always guarantee that? Remember, it may be a race against some piece of code that's not yet written, by an author who doesn't realise what _you_ are doing here because their changeset doesn't intersect with yours. Remember: you have, in effect, made the usage count on that structure non-atomic. I do something like that in rwsems and it's something I have to be very careful about. The main reason I can get away with it is that the actual implementation of rwsems is small and is located in a very restrictes set of places and it's not intermingled with other stuff.
