By "guaranteed", I assume you mean guaranteed within the context of how today's code works. That's good, but this seems like something I would need to keep a close eye on should the architecture change at some point in the future. (Yes, I know - there are numerous other portions of the kernel to which this same statement would apply! :^} ) > mike Thanks for checking into this stuff, Fred templin@erg.sri.com
