You are almost correct, but each kernel has two threads, one of which is 
used for interactions with the FrontEnd, Java, etc - basically to handle 
asynchronous callbacks.

Don't forget that you might be able to find a command line utility that 
would do what you want, and you could then invoke it from Mathematica in 
a pretty seamless way.

If you are working on problems of this sort, it may be worth learning a 
little Java.
