[9fans] Different results for the same rc script when using listen1

[Maurício CA]

Hi, all,

This seems like black magic to me.  I've wrote this small example to
try to understand a problem with a bigger script.

    #!/usr/bin/env rc
    if (test 1 -ne 1) {
        echo I am insane.
    }
    if not {
        echo I am not insane.
    }

Obviously, when I run it, I get:

    I am not insane.

However, using (where 'listen_test.rc' is the name I gave this
script):

    listen1 'tcp!localhost!8080' ./listen_test.rc

and

    echo Hi | dial -e 'tcp!localhost!8080'

what I get is:

    I am insane.

How can running a script throw 'listen1' can get 'rc' to fail an 'if'
test?!?!

Thanks for your help,

Maurício
