Just so I'm not confused: you mean that you don't want the process
substitution to be open as file descriptor 0 in /tmp/test.bsh?  The
redirection makes the pipe resulting from the process substitution
file descriptor 0 for the duration of the while loop.  Child processes
inherit file descriptor 0 from their parent.  What would you rather have
as the standard input for the script in this case?
