This is fine, but note that "kill ... 0" sends the signal to the whole
process group, which might have unexpected side-effects.

Bash and ksh93 manage process groups differently than zsh; this is
related to the way zsh runs the right-hand-side of pipelines in the
current shell when it can.

I don't know about dash or mksh, but but they must have more zsh-like
group management.
