Thanks again .. but I've looked around at the docs and I don't see how I 
could accomplish the same thing as my example code. Perhaps the main 
problem is that with popen* the parent process goes into the block too, 
and its pipes with the child are closed when it leaves the block. This 
is a problem because I need to start several child forks and be able to 
communicate with them all, and then start and stop them at will from 
there. Any pointers as to how I can / should use popen, or popen2, or 
popen3?
