In fact, it doesn't do the same thing: STDERR is redirected to the
terminal here. For instance:

greux:...ftware/mpfr-trunk> perl -e 'open STDERR, ">&STDOUT"; open STDIN, "cvs status|"; exec "cat > /dev/null";'
cvs status: Examining .
cvs status: Examining o.alpha
cvs status: Examining o.linux
cvs status: Examining o.solaris
cvs status: Examining o.sunos
cvs status: Examining tests
greux:...ftware/mpfr-trunk>
