Hi Vince,

In Pharo there is startup list that is used also when quitting (in reverse upon shutdown).

To register a class :
Smalltalk addToStartUpList: aClass

The class startup behavior should go in class method
startUp: resumingBoolean

The class quit behavior should go in a class method
shutDown: quittingBoolean

Hello
 
In VAST there is a class-side method #exiting which can be implemented in an application and is called just before the image is shut down. I use it to typically implement clean-up code.
 
Is there something similar in Pharo? 
 
If I use aBlock ensure: cleanUpBlock, is the cleanUpBlock guaranteed to run in what circumstances?
