           Summary: Use DeferrableOneShotTimer for deleting decoded data
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: koivisto at iki.fi


When loading apple.com/itunes CachedScript::script() takes ~1% of the web thread time, most of which is under system timer code.

We should use DeferrableOneShotTimer instead of plain Timer as that avoids unnecessary low level timer access.
