I had to debug problems like this when I wrote the metamachine
code that is distributed with GNU Go. (This is the oracle.c code.)

Probably what is happening is that both programs are waiting
for the pipe. Each thinks they've sent a response and is waiting
for a reply. See:

To debug this type of problem, try attaching gdb to the running
processes.  Then you can find out what is happening. Look in the
gdb info manual in the node ``Debugging an already running
process.''
