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.
