 Summary of the bug:
 To limit the cpu usage of ffmpeg I have used the following command in the
 past:
 '''while true ; do pkill -STOP ffmpeg && sleep 0.1 && pkill -CONT ffmpeg
 && sleep 0.1 ; done'''
 This does not seem to work anymore, ffmpeg turns into a zombie process
 after a little while. -loglevel debug does not show anything. I have tried
 the latest git snapshot as well.

 How to reproduce:
 {{{
 % ffmpeg version N-95534-gac0f5f4c17 Copyright (c) 2000-2019 the FFmpeg
 developers
   built with Apple LLVM version 10.0.1 (clang-1001.0.46.4)
   configuration: --enable-libx264 --enable-libx265 --enable-nonfree
 --enable-gpl

 shell #1:
 for i in *.MP4 ; do ffmpeg -loglevel debug -i $i -f null - ; done
 shell #2:
 while true ; do pkill -STOP ffmpeg && sleep 0.1 && pkill -CONT ffmpeg &&
 sleep 0.1 ; done
 }}}
 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
