Depending on your exact use case, this might help:  Have an option to 
ssh that causes it to print the PID of the user process on the remote 
computer.

IIF you use session multiplexing, you can open another shell via the 
same SSH process and easily get the "other" child process (the
sibling)
via "pgrep -P $$": that asks for processes with the same parent PID.

Be careful to quote '$$' so that it's interpolated on the remote
side
only.


Even easier would be 'pkill -P $$', of course...


If you can't use session multiplexing, you might be able to find the 
interesting process via the other arguments to pgrep/pkill - like
"-U",
and/or specifying "-P $(pidof sshd)", etc.
