Ok. I should have seen that the syntax was not coming form the 
Net::SSH::Perl
I have not use Net::SSH2 as you have : for me, there is a big lack to 
the libssh2 library,
and it is the lack of ssh-agent support.
So it could be a stupid suggestion, but have you try to put

    $channel->blocking(0);

at the beginning of your script ?
I remember I had problem without this line.
