How do you figure? pipes are special file types, and st_size is
unspecified in a stat() call on a pipe, so the -s test is unreliable in
the first place. Not to mention there is an inherent race in your script
(did the 'echo ABC' process run before or after the 'test -s
/proc/self/fd/63' builtin of the script?). I maintain that there is no
bug except in your script.
