>Description:
The file make by 'mkfifo' is not good.

The FIFO file in redhat linux 6.1 is very good.

you can see it on linux.

>How-To-Repeat:
I use command 'mkfifo test';
on console1, I run 'cat test';
on console2, I run 'cat test';
on console3, I run 'tee test';
on console3, I type few line;

the result on console1 is different from console2.

I think it is not good.
---------
if I only run 'echo abc > test';
The command is not exit immediately.

>Fix:
I do not know how to fix.

 The output on console1 and console2 should be different. Only one
 of the cat programs should output each line. This is what I see on
 FreeBSD-4.2-STABLE, Redhat 7.0 and Redhat 6.2.

 I see the same effect eith echo as I do with tee.
