            Bug ID: 166832
           Summary: Explore combinations of timeout and work count as a
                    metric for when to end an increment of constraint
                    solving
    Classification: Unclassified

           Version: WebKit Nightly Build
          Hardware: All

            Status: NEW
          Severity: Normal

In steady state, after constraint solving marks something, we just yield to marking. But it seems like we could have a smarter metric, where we yield subject to timeout so long as we have at least one thing of new work but haven't yet hit some minimum quota of minimum work.  For example we might have a mutator mark stack that always has one damn thing in it.  It's probably more profitable to try to
run one extra constraint after that, so long as we haven't been running for too long.
