There's more to it than that.  'killall -STOP emacsclient' works fine and suspends the
emacsclient process as expected.  And C-c C-c in the shell buffer, sending SIGTERM to
the emacsclient process, also works.  What is comint-stop-subjob doing which is more than
just sending the SIGSTOP?

By the way, running emacsclient inside an emacs shell buffer is quite common for me.
For example on 'git commit' or 'git rebase' etc, which prompt for a log message.
Simple version control operations can be done from emacs itself with vc-mode or other
libraries, but sometimes you want to go to the shell and run the raw git commands.
The same is true of other version control systems.
