           Summary: Support autoRevoke Blob option in URL.createObjectURL
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kinuko at chromium.org


The File API now has objectURLOptions.autoRevoke option to automatically revoke Blob URLs created by createObjectURL.
The option defaults to true by spec.

http://www.w3.org/TR/FileAPI/#dfn-autoRevoke

It'd be nice to support this feature as we could expect it might reduce memory leaks on unrevoked Blobs.

Defaulting this true could break existing code so it'd be better to announce/ask on webkit-dev before actually making the change.
