  From the look of it, you're failing to close the client side pipe
descriptors on the parent side after you've forked and exec'ed your new
program you wish to read from.  When the child exits, the close on the pipe
will not be registered since the parent also has an open file handle, thus any
further reads on the pipe will block forever.
