 You can't run something on every subshell, but you can run something
on every interactive subshell. For the people who weren't around for
my discovery process of this last year:
	fn prompt { if (! ~ $cpid $pid) {cpid=$pid; ... } }
This will let you run something every time a new interactive shell
starts up and runs prompt.
