I just stumbled upon a the same bug, I think.
I don't have a nice and clean repro since this happened in /init (ash
based). The code was basically:
find /sys/devices/pci* [...] -exec /sbin/hphelp {} \; &
PID=$!
[more code doing other stuff]
wait "$PID"
(/sbin/hphelp is another ash script.)
wait will never return. Reverting aforementioned commit fixes the
issue.
