What's wrong:
Last night, a user came in to the SIPB office, having had dreadful
trouble with ez. She just wanted to get her paper done... anyway, she
had a file of about 5K.

That 105.7% is a drop from around 150%. Ez was not responding to any
input. This was reproducible - if she started up ez on her file, then
used the arrow keys to scroll down, it would start out slow and
eventually stop reacting altogether. It was handling expose events, it
seems (unless perhaps backing store was set - in any case, hiding it
and exposing it didn't leave holes).
I sigSTOP'ed it and gcore'd it; eichin:cores/core.ez.eichin
has a copy. I didn't copy the user's file, however if you get in touch
with her, the file "test" in her homedir is a copy of the original
"memory" from the time it happenned.
The second RT she tried had no such problems. (the first one
powered itself off - giving her no additional confidence :-)
She had no styles set at all; the paper was mostly long
paragraphs (probably over 1K characters each.)
What should have happened:
Ez shouldn't spin like that. If you can analyze the core dump, please
let me know what you find.
