During the work for 6622424, we took a decision to only trim the task queues after we've finished all root scanning, instead of more aggressively as it was done before. Just in case this causes performance problems (due to excessive overflows), we might want to revisit this approach. Opening this CR to track this.

JDK-8204287 Phase timings not updated correctly after JDK-6672778

Resolved

JDK-8201313 Times of sub-phases of ext root scan may be larger than the sum of individual timings
