It occurs to me that -- again, if my guile-emacs work catches on -- some of the remaining storage management code will probably have to change to be boehm-gc compatible. Maybe I should see what it would take to update Dave's work to the current source base, as yet another project that may have its uses independent of the guile work. > There's also a bit of traffic about it in the > emacs-devel archives. I'm looking now... though most of it seems to be "maybe we should consider doing this" type traffic. There's a report that a "very limited experiment" with XEmacs found it to be slower, but not much analysis of why. And, it (the email report) was seven years ago; libgc may have improved. Ken
