[Glass] Get list of class with most instances and size

[Johan Brichau via Glass]

Hi Mariano,

The following piece of code gives you the list of classes loaded into gem memory with their number of instances (and sorted on most instances first). 
Don’t search for a meaning, the ' _vmInstanceCounts: 2 ‘ is something I got from Dale :)

instanceCounts := (System _vmInstanceCounts: 2) sorted:[:a :b | b value first <= a value first].

cheers
Johan

I think it is not, because sometimes when I get a gem crash with an out of memory I get that table written into the log, therefore, I should have such code somewhere in my gemstone. But I do not have ScanBackup class.
