nohup command won't work with tcltest

Question

I am trying to use nohup to run tcltest script overnight. However, the tcltest seems to disable nohup's function and always terminate my tcltest process after I close the shell.

Example,

[root@demo test]# cat 0199.test

    package require tcltest
    namespace import ::tcltest::*
    test Dummy {} -body {
            for { set i 1 } { $i < 3000 } { incr i } {
                    puts "round $i"
                    after 5000
            }
    } -result 0
    cleanupTests

[root@demo test]# cat all_test.sh

    #!/usr/bin/expect -f
    package require tcltest
    namespace import ::tcltest::*
    runAllTests

[root@demo test]# cat nohup.out

This is a problem with your shell/your nohup. The signal shouldn't be propagated down to the test program. Which shell do you use? — tue, Sep 10 '13 at 07:45
That test will fail BTW; the result of `for` is an empty string and not `0`… — Donal Fellows, Sep 10 '13 at 09:36

How did you invoke nohup? I ssh into a Ubuntu server 13.04 system, created the tests, and issued the following commands:

nohup all_test.sh &
logout

Later on, when I came back, I was able to verify that the test ran all the way through (and failed, but that's another story).
