Compacting GC happens too often
Currently we run trigger a compacting GC when the user had been inactive for 20 seconds. This results in a lot of compacting GCs and probably is causing some of the reports of long GC pauses occurring. We should make this happen only after the user has been inactive for 5 minutes (except on nightly, to improve test coverage). We should also make this a pref so it can be changed easily.

Comment on attachment 8640549 [details] [diff] [review] less-frequent-compaction The next beta of 40 will be the RC. So, this is too late to change anything wrt the gc. This will have to ride the train from 41.
