If GPFS is posix compatible i do not understand why a cat should block the other
cat completly meanings on a standard FS you can "cat" from many source to the
same target. Of course the result is not predictable.

>From this point of view i would expect that both "cat" would start writing
immediately thus i would expect a GPFS bug.

All imho.

Note: You might test which the input_file in a different directory and i would
test the behaviour if the output_file is on a local FS like /tmp.
