Curiouser and curiouser....

I went to bring the job into the foreground so that I could pause 
(Ctrl-Z) it [*]

    $ jobs
    [1]+  Stopped                 sudo updatedb  (wd: ~)
    $ fg 1
    sudo updatedb    (wd: ~)
    [sudo] password for mark:

So it looks like I must have run
    sudo updatedb &
.. and sudo needed my password, which it couldn't get in the background. 
Understandable in itself, but why would it need such a high cpu level to 
do nothing?

[*] Incidentally, is there an equivalent to fg for pausing a background job?
