problems with very long alt text

With remote stylesheets off and images off, opening
http://www.dillo.org/test/long_alt_text.html
and dragging the horizontal scrollbar left and right
for a little while will make my machine suddenly start
to page madly.

from what I could see from valgrind and top, nothing
looked amiss in dillo or X, but even after dillo
can finally close (if it can), too many resources are
tied up somehow and I need to restart X to have a really
usable system.

I changed the alt text back to using drawText(), and it
didn't matter much that I could see.

I tried using a width of 16K instead of the 25K or so that
was the real value. This didn't seem to help either.
