I think you have misread the GPL: just because your non-GPL code *can* be 
used with something covered by the GPL doesn't mean your code is infected 
by the GPL. Your code doesn't require a GPL module to run (you can use a 
version of cmd compiled without readline), and you aren't attempting to 
distribute it with a GPL module, so you don't need to care how the end user 
chooses to run it.
