            Bug ID: 172186
           Summary: [iOS] The Garbage Collector should rely on the bmalloc
                    scavenger for up to date memory footprint info
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: msaboff at apple.com

Change set r216763: <http://trac.webkit.org/changeset/216763> introduced code to read memory footprint info from the kernel and respond when the process's memory allocation is getting close to the expected available memory.  In that change set, the GC relies on scavenger updating the footprint value in timely manner.  That is not always possibly, primarily due to allocation patterns.  The GC code should also update the footprint value in a timely manner.
