Ok, what I'm asking for is: "please reserve one bit for me in tp->flags" (31 preferred) and "please reserve 8 bits for me in ml->flags" (24-31 preferred). The latter will also not degrade performance, since these bits shalt simply not be used, but if STACKLESS isn't defined, there is no need to mask these bits off. I also will name these fields in a way that makes it obvious for everybody that they better should not touch these. Iff you agree, I'm going to submit my patch now, and my thanks will follow you for the rest of the subset of our lives. :)
