This is meant to be a correction of the status that I reported earlier. This bug was tricky, and this is only a partial fix due to the recent conservatism. The version of code that I am running on my development machine has low level object locks for better future SMP support, and in fact is needed for "correct" UP operation also, but the code being committed tonight is only a minimal fix for the problems that people have been running into recently. Initially, it looked like the split code was at fault, and like typical it seems that the problem travelled around in the system :-(. There are about 6-7 ugly problems in the VM code that are serious enough to cause crashes, but this only fixes a couple of them, and I will not be committing the more intrusive, complete and more seriously needed fixes until Saturday. (I have the fixes running on my machine, but again due to conservatism, the fixes will not be available for a while.) The worst of the minor bugs, ended up to be an edge condition not directly in the split code, but for an associated free operation on unneeded swap space. So, be forewarned, there will be some serious improvements in the VM code locking mechanisms coming in on Saturday or Sunday, and there might (will) be some instability (but accompanied by significant improvements) then. The fixes being committed in a few minutes will only fix some minor, but irritating problems (and the "netscape" under X problem.) -- 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.
