Maybe a mail to majordomo-owner would help?

No releant change I am aware of.

The "progressivlely slower" during generation of the file is easy to
understand - showlist() uses an inefficient meothod for traversing the
list, it calls HText_childNumber() for each link which traverses the list
from the beginning for each call.  It could be changed.  But maybe it's
a feature - it makes it damage somewhat self-limiting, so you have time to
watch...

All it should take is a HTCheckForInterrupt() in the
        for (cnt = 1; cnt <= refs; cnt++) {
loop in showlist() in LYList.c, plus some sensible action in case it
returns TRUE.  A prompt would make sense, asking whether to show the
partial file (return 0) or not (return -1).

If you care about it, you'll send a patch. :)
