these look like genuine fixes, but i dont think they can explain the hangs i had yesterday - those were simple VM deadlocks. I dont see any deadlocks today - but i'm running the unsafe B2 variant of the vmfixes patch. (and i have no swapping enabled which simplifies my VM setup.)
but one of these two fixes could explain the slowdown i saw on and off for quite some time, seeing very bad read performance occasionally. (do you remember my sched.c tq_disc hack?)
