But annoying. It's corrupting the ps display and there's no way to killall
those threads.

I normally run the build:
(cat /dev/zero | ./buildscript.sh > out.txt 2>&1 &) && tail -f out.txt
(Because the standard "tee" is buggy; it stops sending to a pipe if that pipe
is ever full, which can happen due to the process it's feeding not getting
scheduled fast enough. This includes your xterm. I fixed this in the
busybox version...)
In the above, buildscript runs UML, which exits (with a panic) but doesn't
_stop_. Also "killall linux" will sometimes leave the garbage threads in T
state, and when you -CONT them they turn into CPU hogs.
