Some of the bugs can lurk for years (literally), and even obviously safe changes in my view can be WRONG. Right now, to fix this problem, I am forsaking everything that I can to move forward. If I was sitting idle, I could understand frustration, but right now, we really do need both the sig-(6,11) fixed, and also the split code (for now, Alan Cox from cs.rice.edu came up with a potentially cleaner concept) needs to be in there. Alan's ideas will be better in the future, but right now we need what we have. Also, without this stuff being brought into the public, there is a chance that I wouldn't have gotten as much support. If we didn't need the "fixes", I would have happily backed the code out. If it ends up being a liability for much longer, I'll do something to make things better, but right now, disabiling the split mechanism as-is doesn't fix the problem. I understand the problem, and sometimes things get in my way also. I know that I am about the worst transgressor in this regard, but will try to patch around the signals if I cannot fix it by later on today (right now it is AM EST on Sun.) I do NOT want to get in JB's way, and I have some more, less central VM things to do also. -- John | Never try to teach a pig to sing, dyson@freebsd.org | it just makes you look stupid, jdyson@nc.com | and it irritates the pig.
