I can only think of named pipes (`mknod foo p') with `read var <foo' and
`print go >foo'.

If the pid of the waiting shell is known, one can also use one of the
USR-signals. Or start a endlessly running process in the wait-shell,
wait for it and kill it from the other shell.


We really need that generic socket module ;-)
