[support] passing vars part 2

[aurfalien at gmail.com]

Hi,

So I've taken it a step farther by doing this;

exec('sudo /path/create_user.sh '.($username));

But I would like to back ground this so it doesn't hang the process if  
it should fail.  Plus I read thats its advisable to back ground exec  
calls.

I've tried several incarnations w/o success.

Any ideas?
