$! is the pid of the last process placed into the background by the
shell's job control.  From the shell's perspective, "ssh -f" runs in
the foreground briefly then exits (after forking a copy of itself to
run in the background, but that's not something the shell has
visibility into).  Shell job control is not involved, so $! is not
set.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
