Hi Davis,

I finally looked at your changes. :) So far, they are reasonable. However, the mere wish for not just entering parent projects for recovery but any other introduces a complexity that I am not really happy with. The class var EmergencyRecoveryRequested requires you to:

- take care of the code for set/clear EmergencyRecoveryRequested across multiple methods
- makes the super call in #finalExitActions: mandatory, which is dangerous in my opinion and easy to miss in new kinds of projects

The whole reason for this change is that we think that programmers are not able to establish a safety net of different parent projects on their own. Yet, we should rather pre-configure parent projects for the next release so that nobody has to worry. Maybe the SqueakShell at its root project.

So, overall, this is a -1 from me here. Sorry. 

Here is another take on #tryOtherProjectForRecovery:  What about creating a new project of a different kind? Or re-ordering existing projects as parents? Nevertheless, I think that we should just pre-configure parent projects.

If no objections, I will merge this into trunk in another day or so.
