I think my employer would like me to get back to work. :-) I won't
respond for several more hours, most likely. Anybody who has a clue,
feel free to jump in!
It looks to me like everything is in the X code, not in XEmacs. Am I
reading the output wrong, or are there no XEmacs calls at all there?
If the AIX X code is even just a little bit sucky, I know that XEmacs
calls redisplay far too often, and that could lead to bad performance.
Something seems really broken in the way that XEmacs is linked to the
AIX libraries. Crashes, performance issues. It just doesn't stop
coming. We really need somebody who knows AIX.
It's quite possibly an XEmacs bug, or at least XEmacs doing something
that is usually reasonable, but not on AIX. But I strongly suggest
that the OP should try to get somebody who knows AIX pretty well to
look at this. The redisplay problem mentioned above is not going to
get fixed quickly, it's pervasive since the widgets work.
