}     Thanks again. This is my perfect solution. Putting an extra line
}     killall -USR2 zsh in the ip-up script made it all happen.
} 
}     Also, I am just wondering, are all these features unique to zsh, or
}     other shells have got them as well?

All Bourne-shell-like shells have the "trap" command.  As far as I know,
zsh is the only one that uses magically-named TRAPxxx functions.

Csh-like shells generally handle only INT and TERM signals, and then only
in scripts, not interactively.

Why not simply execute the trap handler code (e.g. the "case" above) in
your .zshenv file, to set the variable properly as each shell starts?
