Opening one end of a FIFO blocks until the OTHER end is also opened.
This is why the first process to open the FIFO should be launched in
the background (it is going to block), if both ends are coming from the
same parent script.
I'm assuming that when you speak of "cat" you mean a process that opens
the FIFO for reading.
