Either you are wrong or the docks are wrong:

pipeProcess also spawns a child process which runs in 
**parallel** with its parent. However, instead of taking 
arbitrary streams, it automatically creates a set of pipes that 
allow the parent to communicate with the child through the 
child's standard input, output, and/or error streams. This 
function corresponds roughly to C's popen function.
