Yup.

I plan on adding a configure parameter --puresize-tolerance to allow
for control over that.  I am dead set on allowing the wastage to go to
0 for distributed stable versions if it can be done.

The initial patches were for proof of concept.

This already happens if the initial PURESIZE is too low and XEmacs
doesn't drop core during the first load phase.

As am I, but how many end users rebuild XEmacs regularly?  Consider my
own installation:

$ ll =emacs-19.34
-r-xr-xr-t   2 root     root      2099198 Aug 25  1996 /usr/local/bin/emacs-19.34*
$ ll =xemacs-19.14
-r-xr-xr-x   1 root     root      3086835 Jun 22  1996 /usr/local/bin/xemacs-19.14*

The point is made that beta versions should be developer friendly.

I'm hoping someone who knows how to do this properly gets inspired
once this mechanism is in distributed betas. :-)

Next on the list btw, is a mechanism for site-load.el to communicate
with make-docfile so that end-user dumped w/XEmacs packages get their
DOC strings properly snarfed.
