I have just modified XEclipse to deliver a warning message and to deny
committing pages which have been expired (overriding others work). The user
can then revert his changes or manually do the changes. This is not a
complete solution but I believe it works for the moment.

Also, I should mention that after this release, XEclipse need to be
refactored and re-designed a bit to accommodate for future changes. Recent
additions and modifications have made the code bit dirty and it will be hard
to maintain it if we do not refactor it now. Once we have a solid design, it
will be easy to extend the product. I think Fabio agrees with me.

Also, I could not find a way to close all active editors when required (for
an example, when the connection is removed). While this is a minor thing, it
can be unpleasant for the user. I wish someone could fix it.

Ok then, I'm going home for a week (at last!). Catch you all later :)
