[Pharo-dev] What is a ExclusiveWeakMessageSend?

Hi Gary

We are working with alain on removing all the triggering event facilities from Object and porting it to announcement.
Now I was wondering what is the ExclusiveWeakMessageSend.

Hi,
It is used in DiffMorph so that the two text panes have their scrolling
synchronised
without infinite recursion (scroll source pane, dest pane matches (and
exclusive prevents source pane being told to match dest pane etc.)).

Regards, Gary
