Definitely not in this case. Similarly, there are a number of early allocations that occur by declaration, rather than by process, where the page mappings are then established post-facto, where it won't work. I really need to publish my "early life of FreeBSD" article. 8-(. I have all my extensive notes together, but I think it's at least a three-parter, and I need to expand the examples. I'll get around to it eventually, I promise. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
