I'm not seeing this, exactly. Can you supply code to demonstrate? To test, I added the following to t_pipeio.e (line 32): 

printf(1, "process pid: %d\n", p[PID])  
system("ps -ef | grep eui")

Reviewing the output, I get: 

process pid: 2419 
matt      2416  2099  0 16:05 pts/0    00:00:00 ../4.0/eui t_pipeio.e 
matt      2419  2416  0 16:05 pts/0    00:00:00 /bin/sh -c ../4.0/eui ../demo/pipe_sub.ex 
matt      2422  2416  0 16:05 pts/0    00:00:00 sh -c ps -ef | grep eui 
matt      2426  2422  0 16:05 pts/0    00:00:00 grep eui 
matt      2427  2419  0 16:05 pts/0    00:00:00 ../4.0/eui ../demo/pipe_sub.ex

It looks like we're getting the PID of the shell that's being used to execute the actual command. I suppose this is because we're executing like this: 

    exec_args("/bin/sh",{"-c", cmd}, pipe)

I'm guessing we do this so that we don't have to separate the command from the arguments of whatever the user actually wants to run?

No response in over a year. I'm calling this one invalid.
