bin/55346: /bin/sh eats memory and CPU infinitely
Hi!
It seems /bin/sh in 4.8-STABLE has problem with SIGCHLD processing.
In short, it often fails to process it correctly, zombies float
around, jobs are not marked as finished in jobtab[] that fills memory
and takes much CPU to be processed.
Run this one-liner using /bin/sh and see hundreds of zombies:
#!/bin/sh
while :; do : & done
A kernel will halt this as soon as it reaches limits and
