Consider the following /bin/sh script:

echo finished | (sleep 15 ; cat)

Compare that with the following icon program:

procedure
main (args)
    local output

    if not (output := open ("sleep 15 ; cat",  "wp")) then
	stop ("trmsg: can't open a pipe for writing")
    write (output, "finished")
    return
end

I believe they should be functionally equivalent.
They're not.  The shell script waits for the cat,
while the icon version exits immediately after
writing to the pipe, without waiting.

I think this is an obvious bug.
If you don't agree, I will be happy to explain more fully.
