Por que existem muitos processos zumbis no subsistema Windows para Linux (WSL)? Como matá-los totalmente?

Recentemente, descobri que meu WSL (ZSHELL) custa muitos recursos de CPU (cerca de 35%) por meio do gerenciador de recursos do Windows.

Então tento descobrir e resolver esse problema da seguinte maneira:

Não funciona.

Descobri que os processos zumbis awkocorrem depois que uso o comando z.

Estou executando o Microsoft Windows 10 Pro (64 bits), versão 10.0.18362 e ainda recebo processos zsh não autorizados. Esta função elimina os processos zsh não autorizados.

killzshs(){ps ax -o pid,command,ppid | grep '.*zsh.*\s1$' | awk '{print $1}' | xargs kill -9}

Em seguida, chame killzshsou coloque a função em seus dotfiles.
