Subject: Re: how can I start a shell process and return immediately?

I have another quetion related to fire off a back ground shell process 
on a remote Linux.

    require "net/ssh"

    ssh = Net::SSH.start( '10.0.77.87', 'toor',  :password=>'logapp')
    ssh.exec!("/root/test.pl &")
    ssh.close
    puts "I want to be here immediately, but not"

The above code hangs also because test.pl contains a long sleep and do 
nothing. Can someone offer me a help?

Thank you in advance.
