As long as I am not completely filling swap, is there any way
that Emacs could even be aware of how much memory I have on the
machine?
well, i could continue wallowing in my ignorance, but source is
available, so i looked in src/alloc.c. you will probably want to
do (setq gc-cons-threshold SOME-LOWER-NUMBER), based on:
| gc-cons-threshold is a variable defined in `src/alloc.c'.
| Its value is 400000
|
| *Number of bytes of consing between garbage collections.
| Garbage collection can happen automatically once this many bytes have been
| allocated since the last garbage collection. All data types count.
|
| Garbage collection happens automatically only when `eval' is called.
|
| By binding this temporarily to a large number, you can effectively
| prevent garbage collection during a part of the program.
| See also `gc-cons-percentage'.
basically, by tweaking this (and perhaps some other gc-FOO vars),
you can make "enough" satisfiable only when it includes the dead frame.
Do you mean the database interface stuff? That brings back
memories! I last hacked on that in 1992 (I think it was 1992),
before Emacs 19 came out.
yes, i revived it in 2004: <http://www.gnuvola.org/software/edb/>.
there were some very twisted things mernst did, but it's ok now.
perhaps one of these days EDB will find itself in a git repo or two.
