It sounds like what I assumed ACT must be doing. How much performance penalty will always pushing the arguments to the stack bring? Will the kernel be compiled with this option, or will you have a separate "checked build" sort of kernel that developers can boot when they are tracking down problems? BTW, thanks for outlining the method for getting function arguments in your blog. I'm hoping I won't need it ;) Thanks, Drew
