What's interesting about this is that it started not all that long ago
- -- before that, the graphs were instantaneous. I can't really figure
out when it started though. I'm guessing it occurred as a result of a
Solaris upgrade, but it's peculiar to me that this should be a problem
even with a lot of fonts. What system *doesn't* have a lot of fonts?
But thank you for the suggestion to see if they exist/how to see what
fonts are required.

My first thought is that maybe recompiling this would help.
