Why don't you just use SSH for that? 
ssh localhost -f -S -L $localport:$proxy:$proxyport

and it does exactly what your script is trying to do. But I'm still confused if that is what you want to do, as I see little use for it.

I was dreaming of guitarnotes that would irritate an executive kind of guy (FZ)

Update: The -S option of SSH makes sure it doesn't try to connect, only functions as portmapper. Moreover, I forgot the supply 'localhost', and the -f option is handy as well.
