Hard for me to tell, personally. Given it has been around for a while, probably low. It seems, based on the stack trace and comments on some of the code, to happen during root scanning on the thread stack during GC? There are other circumstances, but the amount leaked should be relatively low I think.

@coleenp or somebody who knows more than I may have a better idea of when these could be triggered.
