It fixes the problem while also simplifying the condition variable implementation a lot, making the code much easier to rea= son about. I much prefer this fix over my last submission. Let me know if there= is something I need to do to get this reviewed. (I got no feedback on my last submission) I think the review on this will be much easier than on any of t= he other patches so far, because the new condvar implementation is so much simpler. --=20 You are receiving this mail because: You are on the CC list for the bug.=
