Yes. I know that. From the API design and implementation (named as
`killExecutors`), I'd prefer more general case. In case someone else calls
that in the future. Besides, batch kill is better than kill them one by one
each time. If it is ok not to take that account, I will handle that according
to existing case.
Thanks for your comments and suggestions. I will change the code
accordingly.
