    What do I do? I run rc -l in all my windows. Do I notice the slowdown?
    No way! Let's see....

I have a 181 line system .rcrc (it's pretty hideous) and a 66 line personal
one and both get sourced in every xterm I invoke:

    prl313 ; sed 2q .rcrc
    . /proj/ultrix/lib/system.rcrc
    
    prl313 ; wc /proj/ultrix/lib/system.rcrc
         181     468    3674 /proj/ultrix/lib/system.rcrc
    prl313 ; wc .rcrc
          66     143    1051 .rcrc

I have about 40 windows open now, on about 6 machines, but most of them are
on my own machine.  Do I see a slowdown?

    prl313 ; time rc -l /dev/null
            0.9 real         0.0 user         0.4 sys

The bulk of the time I'm waiting is for X to _give me that window_!

On the question of a root prompt, it's just:

    if (test -w /)
    {
    	pc='#'
    } else {
    	pc=';'
    }
    
    prompt=($MACHINE' '^$pc' ' ' ')

End of story.  It's dead cheap.

So cheap, I reckon it's another argument for rcmain.
