           Summary: WebKit could benefit from a JavaScript live object
                    profiler
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: opendarwin.org at bdash.net.nz


With AJAX applications becoming more common, users are spending considerably
longer times on the same page.  If their JavaScript code is poorly written,
they may end up creating a large number of live but unused JavaScript objects
that remain in memory.  It could be useful to be able to view the number and
types of live objects to determine if objects are hanging around longer than
anticipated, so that increases in memory footprint can be limited.
