Xft performance with XEmacs 21.5.28 on Mac OS 10.5

[William Gallafent]

Well, I did a quick "Sampler" run.

I just pressed page up and page down a few times, and all the time  
spent was redrawing the text on the screen.

This time is apparently being spent in "poll$UNIX2003" from _XRead <-   
_XReply <- XQueryColor <- xft_convert_color, and "select 
$DARWIN_EXTSN", from XtAppProcessEvent <- emacs_Xt_next_event.

Anybody know why this might be?

(There is a message with the actual Sampler run attached  (24KB  
zipped!) awaiting moderation ...)
