A user can also be niced by login classes:

    gccuser:*:1000:0:interactive:::gccuser:/home/gccusr:/bin/csh

with /etc/login.conf (less /etc/login.conf, man login.conf, man 5
passwd, /handbook/users-limiting.html):

interactive:\
        :priority=20:\
        :tc=default:

To renice interactively, you can su - gccuser, do so manually, or
spawn/exec the current login shell:

    exec bash --login

with ~/.bash_login:

    renice 20 $$
    export PS1="[\u@\h:\j:\w]\$ "

But be sure not to nice background processes -- it might break the
warrantee....
