I'm not sure why you are using backticks and trying to print the result since you are trying to background the job, but I'm not sure that matters.

I'm no ssh guru, but I'm assuming ssh is keeping the session open since stdout and stderr are still open. If I redirect stdout and stderr, it seems to work ok for me on Linux. You may also want to redirect stdin as well. Try something like this... 

print `ssh myhost "nohup nice perl script.pl </dev/null >/dev/null 2>&
+1 &"`;

Another option might be to backround the ssh process on your local machine instead (though these will of course accumulate).
