bash and read -u

The ksh read builtin has a really nifty -u N option to get input from
filedescriptor N instead of from stdin.  It would be useful if bash
read got that option, too.

Example:

while read -u3 host; do
      echo host: $host
      ssh $host uname -s -r # this command may mess with stdin
done 3<<EOM
