            Bug ID: 165910
           Summary: Make the collector's fixpoint smart about scheduling
                    work
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore

          Reporter: fpizlo at apple.com

The GC currently scans a bunch of things in each fixpoint iteration.  It will sometimes do many fixpoint iterations.  I suspect that when it does have to perform multiple fixpoint iterations, it's because some specific part of the fixpoint is being very needy.  This implies that we can dramatically improve the fixpoint's performance using traditional fixpoint optimization tricks.
