Great, the bug does not occur when KTR is enabled. The machine has been
up for 14+ hours without crashing, despite plenty of network activity,
which usually triggers a freeze within minutes.
It looks like there may still be short freezes (a few seconds at a
time). I'm thinking of instrumenting fetch(1) to record any instances
of fread() taking more than, say, half a second.
