slow fontlocking

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. Please describe as succinctly as possible: - What happened. - What you thought should have happened. - Precisely what you were doing at the time. Please also include any C or lisp back-traces that you may have. ================================================================ Dear Bug Team! What has happened to fontlocking? I switched from XEmacs 21.1... to 21.4.6 and my fontlocking slowed down by a foctor in the order of 10. In the stable version files just opened now I've got to wait for about 10 to 15 seconds for some ordinary files. The fancy progress bar is only cold comfort for this annoying behaviour. Also lazy shot is no real alternative, because then all scrolling and isearching becomes slow. Please make fonlocking fast again. Norbert P.S. I'm using the ProofGeneral mode with XSymbols. www.proofgeneral.org ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux eeyore 2.4.17-rc1 #2 Sun Dec 16 17:50:34 EST 2001 i686 unknown ./configure '--with-sound=none,native' '--cflags=-O2 -g -Wall' '--with-x11' '--extra-verbose' '--with-site-lisp' '--statedir=/var/lib' '--infodir=/usr/share/info/xemacs-21.4.6' '--prefix=/usr' '--error-checking=none' '--debug=no' '--dynamic' '--without-postgresql' '--with-gpm=no' '--with_menubars=lucid' '--with_scrollbars=lucid' '--with_dialogs=athena' '--docdir=/usr/lib/xemacs-21.4.6/i386-debian-linux/mule/' '--with-mule' '--with-canna=no' '--with-wnn=no' '--with-xim=xlib' '--with-xfs' '--package-path=~/.xemacs:~/.xemacs/packages:~/.xemacs/xemacs-packages::/usr/share/xemacs21/packages:/usr/share/xemacs21/mule-packages:/usr/share/xemacs21/site-packages' 'i386-debian-linux' XEmacs 21.4.6 "Common Lisp" configured for `i386-debian-linux'.
