Hi Mariano--

     No, I modified the garbage collector to avoid marking methods which
haven't been run since a chosen point in time. To make a minimal image,
I take a full image, kill unwanted processes remotely, clear all method
activation marks, run a few things I know I'll want (mostly support for
remote messaging), then make a snapshot. The garbage collector runs,
removing unrun methods, causing a chain reaction of unused object
removal, via the freeing of unused method literals. What used to take
days (shrinking manually with a remote system browser) now takes a
couple of seconds.

     I first reported this in February 2006; see [1].

> Finally, which is the license of Spoon? can we see the code?

     I use the MIT license. The current release is at [2], but I've been
too busy to make a release for a while.

> Thanks in advance and best regards...

     Greetings from my new apartment in Amsterdam!
