Hi--
Today I unloaded all the compiled methods which hadn't been run since just before the previous snapshot, made a snapshot, and compressed it with bz2. I added a bz2 decompressor to the virtual machine, and successfully ran the snapshot. The snapshot size on disk is 93,352 bytes ("91 KB"). I consider the snapshot part of the project finished, although I'm sure a few more bytes could be eked out by doing symbol compression, etc. (I'm not going to bother, though, since they make using the snapshot significantly less pleasant).
There is no accurate space analysis for this snapshot, since the act of making one would change the size of the snapshot significantly. :) A space analyzer that ran from a simulator would be useful. When the snapshot is decompressed into RAM, and a space analysis is printed, the space analysis at http://netjam.org/squat/space2.txt is accurate. In summary, the 91 KB file yields a 280 KB object memory, and the system is arbitrarily extensible from there.
Now I'm working on making the smallest possible virtual machine that will run this snapshot.
thanks,
