VACUUM on multi-CPU systems?

Does anyone have any thoughts on whether my database vacuum/full/analyze
might go faster on our 2-CPU system if I generated the VACUUM commands
into a script, e.g.,

psql -a <<EOF
\t
\o /tmp/db_maint.$$
select distinct on (relname) 'VACUUM FULL ANALYZE "' || relname || '";'
from pg_class
where relkind='r'
\g
\o
EOF

(generates a script that looks like

VACUUM FULL ANALYZE table1;
VACUUM FULL ANALYZE table2;

etc.)

and then started two psql sessions each processing half of the file?
