Followup-To:

I just got The Book and a copy of Perl and typed in the "tlist" script on
page 21.  It hung.  After a lot of head-scratching, I finally discovered
that I had a named pipe in my home directory, and that the -T test was 
waiting for someone to write into the pipe.

It seems that -T and -B should return "false" on a named pipe without 
trying to read it.
