1511491 - Don't print out the objects in alphabetical order if many things leak

Status: NEW

Description

[Andrew McCreight [:mccr8]]

The leak logger creates "a comma delimited string of the first N leaked objects found" in order to aid matching in TBPL. The problem is that large leaks can leak dozens of different things, so the first five objects are just random classes. If another class gets added, it looks like a new leak. In addition, all big leaks get bucketed together into a single bug.

At a minimum, maybe the list could just be replaced with "many things leaked" or something like that if the list of leaked objects is really long. Better would be to try to search for interesting objects, like windows and docshells, and mention the number of those that are present.
