Good feedback; I better make that "non-optional" then.

What happens is Java does not use all of your machines memory (without
permission). On the command line you can supply the permission by using
-Xmx1024m - for eclipse they are storing their command line parameters in that
ellipse.ini file.
When java gets close to the limit of memory you have given it; it engages its
garbage collector to try and continue working. Only after trying a number of
times will it actually give up with an "out of memory" error.
If you want to watch what is happening; in your Window > Preferences dialog. On
the general page; you can place a check next to "heap status". It gives you a
nice graph at the bottom of the screen; and has a button if you want to run the
garbage collector yourself.
