Unable to disown process

I have the following script that I use to tunnel nntp traffic:

    nohup ssh -NL 1119:news.mozilla.org:119 \
          -L 2119:news.gmane.org:119 \
          -L 3119:nntp.perl.org:119 \
       andrew@defaria.com > /dev/null 2>&1 &


If I run this script it works fine and I'm tunneled. The problem is I 
cannot exit the terminal in which I invoked this script. When I attempt 
to do this the terminal hangs. I can close the terminal (mintty BTW) 
forcefully and the ssh session remains but it was my understanding that 
disown should allow you to exit the current shell with the 
backgrounded/disowned process continuing to run. In fact I tested this 
on RHEL and it worked as expected. What's up with Cygwin?
