If you plan on using that code again... I'd like to comment...

I find this a pretty non-standard behavior. Running start-tor-browser in
a shell is a bit like typing a command such as "iceweasel", "firefox",
or "torbrowser" in the shell. Usually in Linux world commands don't exit
and keep running in background when started that way. If a user wishes
to have that behavior, they usually add "& disown" to their command, I

So why not go for a simpler, more standard approach, launch it into
background (&); then wait (wait "$pid"); then check return code of wait;

Good point.

Sounds good.
