I'm currently more concerned about the kernel crashes they started
sometime in November if I read Andreas reports right kern/45677 and
kern/46096
In case of 46096 I poked through the crashdump and there seems to be
pool corruption pr_itemoffset is clearly wrong. I haven't yet found a
code path that could have caused that. The crashes reported in 45677
seem very similar in that case. I tend to agree with Martin on that issue.
I'll try to free some time to fix the uvmwait issue but keep in mind the
test tests rump code not the kernel code...
